-OpenVINO Int8 Workflow In a Nutshell
------------------------------------
-To operate with int8, all the data (weights, inputs, activations, etc) should be carefully quantized. The quantization process is driven by:
-
-* Normalization (or scaling) factor, determined by range of the data
-* Quantization level, which depends on whether data is signed or unsigned, and destination precision.
-
-OpenVINO supports two main sources of this information, and thus two main sources of the int8 models:
-
-* Conversion of the framework-quantized models. This approach relies on the training for low precision and subsequent conversion of the resulting model with [Model Optimizer](https://docs.openvinotoolkit.org/latest/_docs_MO_DG_Deep_Learning_Model_Optimizer_DevGuide.html) tool. This approach usually gives optimal accuracy and performance, but requires careful model re-training/fine-tuning. Then for inference, both normalization and quantization factors are deduced fully from the model data (e.g. FakeQuantize layers) and no additional steps are required.
-
-* Post-training quantization of the floating point models with the [Calibration tool](https://docs.openvinotoolkit.org/latest_docs_IE_DG_Int8Inference.html#low_precision_8_bit_integer_inference_workflow). Just like approach described earlier, the calibration is also fully offline additional step to equip a model with (optional) int8 information.  The approach is somewhat more universal, requiring just floating point model and no retraining to leverage the int8. The calibration is iterative process of gathering _activations_ statistics like histogram (for determining scaling/parameters), applying the quantization parameters and evaluating resulting model accuracy to keep it as close to original as possible. For _weights_, in contrast, the maximum abs value per output channel m is found. The per-channel range is then [-m,m]. This calibration process trades the performance vs accuracy and results in a mixed precision model which are a combination of fp32 (high accuracy) and int8 (high performance) layers.
-
-Notice that OpenVINO assumes the symmetrically quantized models (with respect to weights) and either symmetric (signed) or fully unsigned activations.
-
-Quantized Model Example
------------------------------------
-For the MLPerf 0.5 submission, the only directly converted quantized model is ssd-mobilenet from Habana ("ssd-mobilenet 300x300 symmetrically quantized finetuned"), referenced at https://github.com/mlperf/inference/tree/master/v0.5/classification_and_detection.
-
-To convert the model, just call the [Model Optimizer](https://docs.openvinotoolkit.org/latest/_docs_MO_DG_Deep_Learning_Model_Optimizer_DevGuide.html). There are certain specifics for [converting The TensorFlow Object Detection API models](https://docs.openvinotoolkit.org/latest/_docs_MO_DG_prepare_model_convert_model_tf_specific_Convert_Object_Detection_API_Models.html). For example, the original pipeline.config is needed. For the symmetrically quantized it is actually the same as for another Habana's model  ("ssd-mobilenet 300x300 quantized finetuned").
-
-Conversion command-line is as follows:
-```
-$ python3  <OPENVINO_INSTALL_DIR/deployment_tools/model_optimizer/>mo.py
---input_model <path_to_model/>ssd_mobilenet_v1_quant_ft_no_zero_point_frozen_inference_graph.pb
---input_shape [1,300,300,3]
---reverse_input_channels
---tensorflow_use_custom_operations_config <OPENVINO_INSTALL_DIR/deployment_tools/model_optimizer/>extensions/front/tf/ssd_v2_support.json
---tensorflow_object_detection_api_pipeline_config <path_to_model/>pipeline.config
-```
-
-Model Calibration Example
------------------------------------
-To give an example of the [calibration workflow](https://docs.openvinotoolkit.org/latest/_inference_engine_tools_calibration_tool_README.html), let's consider ResNet-50 (v1.5) example ("resnet50-v1.5	tensorflowfp32 NHWC").
-
-* First, the model is converted from an original framework format using the Model Optimizer tool. Since this is classification (and not detection) model, the command-line is really simple:
-
-```
-$ python3  <OPENVINO_INSTALL_DIR/deployment_tools/model_optimizer/> mo.py --input_model ./resnet50_v1.pb --input_shape [1,224,224,3] --reverse_input_channels
-```
-
-This outputs the model in Intermediate Representation (IR) format ( *.xml and *.bin file). FP32 is default precision
-(use '--data_type FP16' to get fp16 model instead, which is more GPU-friendly).
-
-* Secondly, perform model calibration using the [Calibration tool](https://docs.openvinotoolkit.org/latest_docs_IE_DG_Int8Inference.html#low_precision_8_bit_integer_inference_workflow). The tool is framework-agnostic and accepts the model in the IR format. Model calibration requires a validation dataset (to keep track of the accuracy during calibration). Currently, the calibration tool comes with example support of classification and object detection  models on ImageNet and VOC2007/COCO data sets respectively and associated accuracy metrics. It is relatively straightforward to add another datasets and metrics.
-
-The accuracy validation in turn comes via [Accuracy Checker](https://github.com/opencv/open_model_zoo/tree/develop/tools/accuracy_checker/accuracy_checker/) tool.
-For that, the dataset specific annotations [are converted in the common format](https://github.com/opencv/open_model_zoo/tree/develop/tools/accuracy_checker/accuracy_checker/annotation_converters).
-Specifically for the ImageNet required for the ResNet, the command-line is as follows:
-```
-$ convert_annotation imagenet --annotation_file <PATH_TO_IMAGES>/ILSVRC2012_val.txt --labels_file <PATH_TO_IMAGES>/synset_words.txt --has_background True
-```
-This outputs *.pickle and *.json files used in calibration via
-[configuration files in YML](https://docs.openvinotoolkit.org/latest/_inference_engine_tools_calibration_tool_README.html).
-Alternatively, you can specify the annotation conversion parameters in the config file and let the calibration tool call the 'convert_annotation' tool.
-Similarly, the calibration tool can either accept the converted model as an IR, or the original model directly and perform conversion on the flight.
-Both ways are governed by the 'launchers' section of the config file.
-
-Care must be taken on the configuration in general, as there are many items like pre-processing
-(mean and scale values, RGB vs BGR), resizing (with and without crop, etc), and so on, that can severely
-affect the resulting accuracy. Notice that the pre-processing applied during calibration should match the pre-processing that is later used for inference.
-Also, the pre-processing parameters (like mean/scale, or RGB-BGR conversion) can be either part of the Model Optimizer cmd-line
-('mo_params' section of the config file) and this will bake the input transformations directly _into the resulting model_,
-or 'preprocessing' section of the 'dataset'. The latter doesn't not include the pre-processing into the model,
-but applies it to _every loaded dataset image_ instead (before using within the calibration).
-The choice depends on your inference pipeline: if the pre-processing is explicitly performed in the code,
-the model shouldn't include that, to avoid double pre-processing.
-
-See example YML files for the MLPerf models in the 'example_calibration_files' folder.
-The files define the original models, govern conversion to the IR, dataset annotations conversion,
-and finally the calibration itself. You only have to patch the paths to your local machines.
-*Notice that the pre-processing is not included into a model
-(and thus assumed to be applied to an input image before inferencing that), see earlier this section*.
-
-Finally, the calibration command-line is as simple as:
-```
-$ python3 calibrate.py
--c <PATH_TO_CONFIG>/resnet_v1.5_50.yml
--M <PATH_TO_MODEL_OPTIMIZER>
--C <PATH_TO_OUTPUT_FP_IR>
---output_dir <PATH_TO_OUTPUT_I8_IR>
-```
-Resulting IR contains original floating point (that all OpenVINO device plugins should support) and (optional) int8 statistics, that some devices might ignore (if int8 is not supported on the device), falling back to the original model.

+## Introduction
+
+The Inference Engine can infer models in different formats with various input
+and output formats.
+
+The open source version of Inference Engine includes the following plugins:
+
+| PLUGIN               | DEVICE TYPES |
+| ---------------------| -------------|
+| CPU plugin           | Intel® Xeon® with Intel® AVX2 and AVX512, Intel® Core™ Processors with Intel® AVX2, Intel® Atom® Processors with Intel® SSE |
+| GPU plugin           | Intel® Processor Graphics, including Intel® HD Graphics and Intel® Iris® Graphics |
+| GNA plugin           | Intel® Speech Enabling Developer Kit, Amazon Alexa\* Premium Far-Field Developer Kit, Intel® Pentium® Silver processor J5005, Intel® Celeron® processor J4005, Intel® Core™ i3-8121U processor |
+| MYRIAD plugin        | Intel® Movidius™ Neural Compute Stick powered by the Intel® Movidius™ Myriad™ 2, Intel® Neural Compute Stick 2 powered by the Intel® Movidius™ Myriad™ X |
+| Heterogeneous plugin | Heterogeneous plugin enables computing for inference on one network on several Intel® devices. |
+
+Inference Engine plugin for Intel® FPGA is distributed only in a binary form,
+as a part of [Intel® Distribution of OpenVINO™].
+
+## Build on Linux\* Systems
+
+The software was validated on:
+- Ubuntu\* 18.04 (64-bit) with default GCC\* 7.5.0
+- Ubuntu\* 16.04 (64-bit) with default GCC\* 5.4.0
+- CentOS\* 7.4 (64-bit) with default GCC\* 4.8.5
+
+### Software Requirements
+- [CMake]\* 3.11 or higher
+- GCC\* 4.8 or higher to build the Inference Engine
+- Python 3.5 or higher for Inference Engine Python API wrapper
+- (Optional) [Install Intel® Graphics Compute Runtime for OpenCL™ Driver package 19.41.14441].
+
+### Build Steps
+1. Clone submodules:
+    ```sh
+    cd openvino
+    git submodule update --init --recursive
+    ```
+2. Install build dependencies using the `install_dependencies.sh` script in the
+   project root folder.
+   ```sh
+   chmod +x install_dependencies.sh
+   ```
+   ```sh
+   ./install_dependencies.sh
+   ```
+3. By default, the build enables the Inference Engine GPU plugin to infer models
+   on your Intel® Processor Graphics. This requires you to
+   [Install Intel® Graphics Compute Runtime for OpenCL™ Driver package 19.41.14441]
+   before running the build. If you don't want to use the GPU plugin, use the
+   `-DENABLE_CLDNN=OFF` CMake build option and skip the installation of the
+   Intel® Graphics Compute Runtime for OpenCL™ Driver.
+4. Create a build folder:
+```sh
+  mkdir build && cd build
+```
+5. Inference Engine uses a CMake-based build system. In the created `build`
+   directory, run `cmake` to fetch project dependencies and create Unix
+   makefiles, then run `make` to build the project:
+```sh
+  cmake -DCMAKE_BUILD_TYPE=Release ..
+  make --jobs=$(nproc --all)
+```
+
+### Additional Build Options
+
+You can use the following additional build options:
+
+- The default build uses an internal JIT GEMM implementation.
+
+- To switch to an OpenBLAS\* implementation, use the `GEMM=OPENBLAS` option with
+  `BLAS_INCLUDE_DIRS` and `BLAS_LIBRARIES` CMake options to specify a path to the
+  OpenBLAS headers and library. For example, the following options on CentOS\*:
+  `-DGEMM=OPENBLAS -DBLAS_INCLUDE_DIRS=/usr/include/openblas -DBLAS_LIBRARIES=/usr/lib64/libopenblas.so.0`.
+
+- To switch to the optimized MKL-ML\* GEMM implementation, use `-DGEMM=MKL`
+  and `-DMKLROOT=<path_to_MKL>` CMake options to specify a path to unpacked
+  MKL-ML with the `include` and `lib` folders. MKL-ML\* package can be downloaded
+  from the Intel® [MKL-DNN repository].
+
+- Threading Building Blocks (TBB) is used by default. To build the Inference
+  Engine with OpenMP\* threading, set the `-DTHREADING=OMP` option.
+
+- Required versions of TBB and OpenCV packages are downloaded automatically by
+  the CMake-based script. If you want to use the automatically downloaded
+  packages but you already have installed TBB or OpenCV packages configured in
+  your environment, you may need to clean the `TBBROOT` and `OpenCV_DIR`
+  environment variables before running the `cmake` command, otherwise they
+  will not be downloaded and the build may fail if incompatible versions were
+  installed.
+
+- If the CMake-based build script can not find and download the OpenCV package
+  that is supported on your platform, or if you want to use a custom build of
+  the OpenCV library, refer to the
+  [Use Custom OpenCV Builds](#use-custom-opencv-builds-for-inference-engine)
+  section for details.
+
+- To build the Python API wrapper:
+  1. Install all additional packages listed in the
+     `/inference-engine/ie_bridges/python/requirements.txt` file:
+     ```sh
+     pip install -r requirements.txt  
+     ```
+  2. Use the `-DENABLE_PYTHON=ON` option. To specify an exact Python version, use the following
+     options:
+     ```
+     -DPYTHON_EXECUTABLE=`which python3.7` \
+     -DPYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.7m.so \
+     -DPYTHON_INCLUDE_DIR=/usr/include/python3.7
+     ```
+
+- To switch the CPU and GPU plugins off/on, use the `cmake` options
+  `-DENABLE_MKL_DNN=ON/OFF` and `-DENABLE_CLDNN=ON/OFF` respectively.
+
+- nGraph-specific compilation options:
+  `-DNGRAPH_ONNX_IMPORT_ENABLE=ON` enables the building of the nGraph ONNX importer.
+  `-DNGRAPH_JSON_ENABLE=ON` enables nGraph JSON-based serialization.
+  `-DNGRAPH_DEBUG_ENABLE=ON` enables additional debug prints.
+
+## Build for Raspbian Stretch* OS
+
+> **NOTE**: Only the MYRIAD plugin is supported.
+
+### Hardware Requirements
+* Raspberry Pi\* 2 or 3 with Raspbian\* Stretch OS (32-bit). Check that it's CPU supports ARMv7 instruction set (`uname -m` command returns `armv7l`).
+
+  > **NOTE**: Despite the Raspberry Pi\* CPU is ARMv8, 32-bit OS detects ARMv7 CPU instruction set. The default `gcc` compiler applies ARMv6 architecture flag for compatibility with lower versions of boards. For more information, run the `gcc -Q --help=target` command and refer to the description of the `-march=` option.
+
+You can compile the Inference Engine for Raspberry Pi\* in one of the two ways:
+* [Native Compilation](#native-compilation), which is the simplest way, but time-consuming
+* [Cross Compilation Using Docker*](#cross-compilation-using-docker), which is the recommended way
+
+### Native Compilation
+Native compilation of the Inference Engine is the most straightforward solution. However, it might take at least one hour to complete on Raspberry Pi\* 3.
+
+1. Install dependencies:
+
+  ```bash
+  sudo apt-get update
+  sudo apt-get install -y git cmake libusb-1.0-0-dev
+  ```
+
+2. Go to the cloned `openvino` repository:
+
+  ```bash
+  cd openvino
+  ```
+
+3. Initialize submodules:
+
+  ```bash
+  git submodule update --init --recursive
+  ```
+
+4. Create a build folder:
+
+  ```bash
+  mkdir build && cd build
+  ```
+
+5. Build the Inference Engine:
+
+  ```bash
+  cmake -DCMAKE_BUILD_TYPE=Release \
+        -DENABLE_SSE42=OFF \
+        -DTHREADING=SEQ \
+        -DENABLE_GNA=OFF .. && make
+  ```
+
+### Cross Compilation Using Docker*
+
+  This compilation was tested on the following configuration:
+
+  * Host: Ubuntu\* 18.04 (64-bit, Intel® Core™ i7-6700K CPU @ 4.00GHz × 8)
+  * Target: Raspbian\* Stretch (32-bit, ARMv7, Raspberry Pi\* 3)
+
+1. Install Docker\*:
+
+  ```bash
+  sudo apt-get install -y docker.io
+  ```
+
+2. Add a current user to `docker` group:
+
+  ```bash
+  sudo usermod -a -G docker $USER
+  ```
+
+  Log out and log in for this to take effect.
+
+3. Create a directory named `ie_cross_armhf` and add a text file named `Dockerfile`
+with the following content:
+
+  ```docker
+  FROM debian:stretch
+
+  USER root
+
+  RUN dpkg --add-architecture armhf && \
+      apt-get update && \
+      apt-get install -y --no-install-recommends \
+      build-essential \
+      crossbuild-essential-armhf \
+      git \
+      wget \
+      libusb-1.0-0-dev:armhf \
+      libgtk-3-dev:armhf \
+      libavcodec-dev:armhf \
+      libavformat-dev:armhf \
+      libswscale-dev:armhf \
+      libgstreamer1.0-dev:armhf \
+      libgstreamer-plugins-base1.0-dev:armhf \
+      libpython3-dev:armhf \
+      python3-pip
+
+  RUN wget https://www.cmake.org/files/v3.14/cmake-3.14.3.tar.gz && \
+      tar xf cmake-3.14.3.tar.gz && \
+      (cd cmake-3.14.3 && ./bootstrap --parallel=$(nproc --all) && make --jobs=$(nproc --all) && make install) && \
+      rm -rf cmake-3.14.3 cmake-3.14.3.tar.gz
+  ```
+
+  It uses the Debian\* Stretch (Debian 9) OS for compilation because it is a base of the Raspbian\* Stretch.
+
+4. Build a Docker\* image:
+
+  ```bash
+  docker image build -t ie_cross_armhf ie_cross_armhf
+  ```
+
+5. Run Docker\* container with mounted source code folder from host:
+
+  ```bash
+  docker run -it -v /absolute/path/to/openvino:/openvino ie_cross_armhf /bin/bash
+  ```
+
+6. While in the container:
+
+    1. Go to the cloned `openvino` repository:
+
+      ```bash
+      cd openvino
+      ```
+
+    2. Create a build folder:
+
+      ```bash
+      mkdir build && cd build
+      ```
+
+    3. Build the Inference Engine:
+
+      ```bash
+      cmake -DCMAKE_BUILD_TYPE=Release \
+          -DCMAKE_TOOLCHAIN_FILE="../cmake/arm.toolchain.cmake" \
+          -DTHREADS_PTHREAD_ARG="-pthread" \
+          -DENABLE_SSE42=OFF \
+          -DTHREADING=SEQ \
+          -DENABLE_GNA=OFF .. && make --jobs=$(nproc --all)
+      ```
+
+7. Press **Ctrl+D** to exit from Docker. You can find the resulting binaries
+   in the `openvino/bin/armv7l/` directory and the OpenCV*
+   installation in the `openvino/inference-engine/temp`.
+
+>**NOTE**: Native applications that link to cross-compiled Inference Engine
+library require an extra compilation flag `-march=armv7-a`.
+
+### Additional Build Options
+
+You can use the following additional build options:
+
+- Required versions of OpenCV packages are downloaded automatically by the
+  CMake-based script. If you want to use the automatically downloaded packages
+  but you already have installed OpenCV packages configured in your environment,
+  you may need to clean the `OpenCV_DIR` environment variable before running
+  the `cmake` command; otherwise they won't be downloaded and the build may
+  fail if incompatible versions were installed.
+
+- If the CMake-based build script cannot find and download the OpenCV package
+  that is supported on your platform, or if you want to use a custom build of
+  the OpenCV library, see: [Use Custom OpenCV Builds](#use-custom-opencv-builds-for-inference-engine)
+  for details.
+
+- To build Python API wrapper, install `libpython3-dev:armhf` and `python3-pip`
+  packages using `apt-get`; then install `numpy` and `cython` python modules
+  via `pip3`, adding the following options:
+   ```sh
+   -DENABLE_PYTHON=ON \
+   -DPYTHON_EXECUTABLE=/usr/bin/python3.5 \
+   -DPYTHON_LIBRARY=/usr/lib/arm-linux-gnueabihf/libpython3.5m.so \
+   -DPYTHON_INCLUDE_DIR=/usr/include/python3.5
+   ```
+
+- nGraph-specific compilation options:
+  `-DNGRAPH_ONNX_IMPORT_ENABLE=ON` enables the building of the nGraph ONNX importer.
+  `-DNGRAPH_JSON_ENABLE=ON` enables nGraph JSON-based serialization.
+  `-DNGRAPH_DEBUG_ENABLE=ON` enables additional debug prints.
+
+## Build on Windows* Systems
+
+The software was validated on:
+- Microsoft\* Windows\* 10 (64-bit) with Visual Studio 2017 and Intel® C++
+  Compiler 2018 Update 3
+
+### Software Requirements
+- [CMake]\*3.11 or higher
+- Microsoft\* Visual Studio 2017, 2019 or [Intel® C++ Compiler] 18.0
+- (Optional) Intel® Graphics Driver for Windows* (26.20) [driver package].
+- Python 3.5 or higher for Inference Engine Python API wrapper
+
+### Build Steps
+
+1. Clone submodules:
+    ```sh
+    git submodule update --init --recursive
+    ```
+2. By default, the build enables the Inference Engine GPU plugin to infer models
+   on your Intel® Processor Graphics. This requires you to [download and install
+   the Intel® Graphics Driver for Windows (26.20) [driver package] before
+   running the build. If you don't want to use the GPU plugin, use the
+   `-DENABLE_CLDNN=OFF` CMake build option and skip the installation of the
+   Intel® Graphics Driver.    
+3. Create build directory:
+    ```sh
+    mkdir build
+    ```
+4. In the `build` directory, run `cmake` to fetch project dependencies and
+   generate a Visual Studio solution.
+
+   For Microsoft\* Visual Studio 2017:
+```sh
+cmake -G "Visual Studio 15 2017 Win64" -DCMAKE_BUILD_TYPE=Release ..
+```
+
+   For Microsoft\* Visual Studio 2019:
+```sh
+cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_BUILD_TYPE=Release ..
+```
+
+   For Intel® C++ Compiler 18:
+```sh
+cmake -G "Visual Studio 15 2017 Win64" -T "Intel C++ Compiler 18.0" ^
+    -DCMAKE_BUILD_TYPE=Release ^
+    -DICCLIB="C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2018\windows\compiler\lib" ..
+```
+
+5. Build generated solution in Visual Studio or run
+   `cmake --build . --config Release` to build from the command line.
+
+6. Before running the samples, add paths to the TBB and OpenCV binaries used for
+   the build to the `%PATH%` environment variable. By default, TBB binaries are
+   downloaded by the CMake-based script to the `<openvino_repo>/inference-engine/temp/tbb/bin`
+   folder, OpenCV binaries to the `<openvino_repo>/inference-engine/temp/opencv_4.3.0/opencv/bin`
+   folder.
+
+### Additional Build Options
+
+- Internal JIT GEMM implementation is used by default.
+
+- To switch to OpenBLAS GEMM implementation, use the `-DGEMM=OPENBLAS` CMake
+  option and specify path to OpenBLAS using the `-DBLAS_INCLUDE_DIRS=<OPENBLAS_DIR>\include`
+  and `-DBLAS_LIBRARIES=<OPENBLAS_DIR>\lib\libopenblas.dll.a` options. Download
+  a prebuilt OpenBLAS\* package via the [OpenBLAS] link. mingw64* runtime
+  dependencies can be downloaded via the [mingw64\* runtime dependencies] link.
+
+- To switch to the optimized MKL-ML\* GEMM implementation, use the
+  `-DGEMM=MKL` and `-DMKLROOT=<path_to_MKL>` CMake options to specify a path to
+  unpacked MKL-ML with the `include` and `lib` folders. MKL-ML\* package can be
+  downloaded from the Intel&reg; [MKL-DNN repository for Windows].
+
+- Threading Building Blocks (TBB) is used by default. To build the Inference
+  Engine with OpenMP* threading, set the `-DTHREADING=OMP` option.
+
+- Required versions of TBB and OpenCV packages are downloaded automatically by
+  the CMake-based script. If you want to use the automatically-downloaded
+  packages but you already have installed TBB or OpenCV packages configured in
+  your environment, you may need to clean the `TBBROOT` and `OpenCV_DIR`
+  environment variables before running the `cmake` command; otherwise they won't
+  be downloaded and the build may fail if incompatible versions were installed.
+
+- If the CMake-based build script can not find and download the OpenCV package
+  that is supported on your platform, or if you want to use a custom build of

+
+## Build on Android* Systems
+
+This section describes how to build Inference Engine for Android x86 (64-bit) operating systems.
+
+### Software Requirements
+
+- [CMake]\* 3.11 or higher
+- Android NDK (this guide has been validated with r20 release)
+
+### Build Steps
+
+1. Download and unpack Android NDK: https://developer.android.com/ndk/downloads. Let's assume that `~/Downloads` is used as a working folder.
+  ```sh
+  cd ~/Downloads
+  wget https://dl.google.com/android/repository/android-ndk-r20-linux-x86_64.zip
+
+  unzip android-ndk-r20-linux-x86_64.zip
+  mv android-ndk-r20 android-ndk
+  ```
+
+2. Clone submodules
+  ```sh
+  cd openvino
+  git submodule update --init --recursive
+  ```
+
+3. Create a build folder:
+  ```sh
+    mkdir build
+  ```
+
+4. Change working directory to `build` and run `cmake` to create makefiles. Then run `make`.
+  ```sh
+  cd build
+
+  cmake .. \
+    -DCMAKE_TOOLCHAIN_FILE=~/Downloads/android-ndk/build/cmake/android.toolchain.cmake \
+    -DANDROID_ABI=x86_64 \
+    -DANDROID_PLATFORM=21 \
+    -DANDROID_STL=c++_shared \
+    -DENABLE_OPENCV=OFF
+
+  make --jobs=$(nproc --all)
+  ```
+
+  * `ANDROID_ABI` specifies target architecture (`x86_64`)
+  * `ANDROID_PLATFORM` - Android API version
+  * `ANDROID_STL` specifies that shared C++ runtime is used. Copy `~/Downloads/android-ndk/sources/cxx-stl/llvm-libc++/libs/x86_64/libc++_shared.so` from Android NDK along with built binaries
+
+
+## Use Custom OpenCV Builds for Inference Engine
+
+> **NOTE**: The recommended and tested version of OpenCV is 4.4.0.
+
+Required versions of OpenCV packages are downloaded automatically during the
+building Inference Engine library. If the build script can not find and download
+the OpenCV package that is supported on your platform, you can use one of the
+following options:
+
+* Download the most suitable version from the list of available pre-build
+  packages from [https://download.01.org/opencv/2020/openvinotoolkit] from the
+  `<release_version>/inference_engine` directory.
+
+* Use a system-provided OpenCV package (e.g with running the
+  `apt install libopencv-dev` command). The following modules must be enabled:
+  `imgcodecs`, `videoio`, `highgui`.
+
+* Get the OpenCV package using a package manager: pip, conda, conan etc. The
+  package must have the development components included (header files and CMake
+  scripts).
+
+* Build OpenCV from source using the [build instructions](https://docs.opencv.org/master/df/d65/tutorial_table_of_content_introduction.html) on the OpenCV site.
+
+After you got the built OpenCV library, perform the following preparation steps
+before running the Inference Engine build:
+
+1. Set the `OpenCV_DIR` environment variable to the directory where the
+   `OpenCVConfig.cmake` file of you custom OpenCV build is located.
+2. Disable the package automatic downloading with using the `-DENABLE_OPENCV=OFF`
+   option for CMake-based build script for Inference Engine.
+
+## Add Inference Engine to Your Project
+
+For CMake projects, set the `InferenceEngine_DIR` environment variable:
+
+```sh
+export InferenceEngine_DIR=/path/to/openvino/build/
+```
+
+Then you can find Inference Engine by `find_package`:
+
+```cmake
+find_package(InferenceEngine)
+include_directories(${InferenceEngine_INCLUDE_DIRS})
+target_link_libraries(${PROJECT_NAME} ${InferenceEngine_LIBRARIES} dl)
+```
+
+## (Optional) Additional Installation Steps for the Intel® Movidius™ Neural Compute Stick and Neural Compute Stick 2
+
+> **NOTE**: These steps are only required if you want to perform inference on
+Intel® Movidius™ Neural Compute Stick or the Intel® Neural Compute Stick 2 using
+the Inference Engine MYRIAD Plugin. See also [Intel® Neural Compute Stick 2 Get Started].
+
+### For Linux, Raspbian\* Stretch OS
+
+1. Add the current Linux user to the `users` group; you will need to log out and
+   log in for it to take effect:
+```sh
+sudo usermod -a -G users "$(whoami)"
+```
+
+2. To perform inference on Intel® Movidius™ Neural Compute Stick and Intel®
+   Neural Compute Stick 2, install the USB rules as follows:
+```sh
+cat <<EOF > 97-myriad-usbboot.rules
+SUBSYSTEM=="usb", ATTRS{idProduct}=="2150", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1"
+SUBSYSTEM=="usb", ATTRS{idProduct}=="2485", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1"
+SUBSYSTEM=="usb", ATTRS{idProduct}=="f63b", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1"
+EOF
+```
+```sh
+sudo cp 97-myriad-usbboot.rules /etc/udev/rules.d/
+```
+```sh
+sudo udevadm control --reload-rules
+```
+```sh
+sudo udevadm trigger
+```
+```sh
+sudo ldconfig
+```
+```sh
+rm 97-myriad-usbboot.rules
+```
+
+## Next Steps
+
+Congratulations, you have built the Inference Engine. To get started with the
+OpenVINO™, proceed to the Get Started guides:
+
+* [Get Started with Deep Learning Deployment Toolkit on Linux*](get-started-linux.md)
+
+## Notice
+
+To enable some additional nGraph features and use your custom nGraph library with the OpenVINO™ binary package,
+make sure the following:
+- nGraph library was built with the same version which is used in the Inference Engine.
+- nGraph library and the Inference Engine were built with the same compilers. Otherwise you might face application binary interface (ABI) problems.
+
+To prepare your custom nGraph library for distribution, which includes collecting all headers, copy
+binaries, and so on, use the `install` CMake target.
+This target collects all dependencies, prepares the nGraph package and copies it to a separate directory.

+# Custom Layers Guide {#openvino_docs_HOWTO_Custom_Layers_Guide}
+
+The Intel® Distribution of OpenVINO™ toolkit supports neural network model layers in multiple frameworks including TensorFlow*, Caffe*, MXNet*, Kaldi* and ONYX*. The list of known layers is different for each of the supported frameworks. To see the layers supported by your framework, refer to [supported frameworks](../MO_DG/prepare_model/Supported_Frameworks_Layers.md).
+
+Custom layers are layers that are not included in the list of known layers. If your topology contains any layers that are not in the list of known layers, the Model Optimizer classifies them as custom.
+
+This guide illustrates the workflow for running inference on topologies featuring custom layers, allowing you to plug in your own implementation for existing or completely new layers.
+For a step-by-step example of creating and executing a custom layer, see the [Custom Layer Implementation Tutorials for Linux and Windows.](https://github.com/david-drew/OpenVINO-Custom-Layers/tree/master/2019.r2.0)
+
+## Terms used in this guide
+
+- *Layer* — The abstract concept of a math function that is selected for a specific purpose (relu, sigmoid, tanh, convolutional).  This is one of a sequential series of building blocks within the neural network.
+- *Kernel* — The implementation of a layer function, in this case, the math programmed (in C++ and Python) to perform the layer operation for target hardware (CPU or GPU).
+- *Intermediate Representation (IR)* — Neural Network used only by the Inference Engine in OpenVINO abstracting the different frameworks and describing topology, layer parameters and weights.
+The original format will be a supported framework such as TensorFlow, Caffe, or MXNet.
+
+- *Model Extension Generator* — Generates template source code files for each of the extensions needed by the Model Optimizer and the Inference Engine. 
+   
+- *Inference Engine Extension* — Device-specific module implementing custom layers (a set of kernels).
+
+
+## Custom Layer Overview
+
+The [Model Optimizer](https://docs.openvinotoolkit.org/2019_R1.1/_docs_MO_DG_Deep_Learning_Model_Optimizer_DevGuide.html) searches the list of known layers for each layer contained in the input model topology before building the model's internal representation, optimizing the model, and producing the Intermediate Representation files.  
+
+The [Inference Engine](https://docs.openvinotoolkit.org/2019_R1.1/_docs_IE_DG_Deep_Learning_Inference_Engine_DevGuide.html) loads the layers from the input model IR files into the specified device plugin, which will search a list of known layer implementations for the device.  If your topology contains layers that are not in the list of known layers for the device, the Inference Engine considers the layer to be unsupported and reports an error.  To see the layers that are supported by each device plugin for the Inference Engine, refer to the [Supported Devices](https://docs.openvinotoolkit.org/2019_R1.1/_docs_IE_DG_supported_plugins_Supported_Devices.html) documentation.

+**Note:** If a device doesn't support a particular layer, an alternative to creating a new custom layer is to target an additional device using the HETERO plugin. The [Heterogeneous Plugin](https://docs.openvinotoolkit.org/2019_R1.1/_docs_IE_DG_supported_plugins_HETERO.html) may be used to run an inference model on multiple devices allowing the unsupported layers on one device to "fallback" to run on another device (e.g., CPU) that does support those layers.
+
+## Custom Layer Implementation Workflow
+
+When implementing a custom layer for your pre-trained model in the Intel® Distribution of OpenVINO™ toolkit, you will need to add extensions to both the Model Optimizer and the Inference Engine. 
+
+## Custom Layer Extensions for the Model Optimizer 
+
+The following figure shows the basic processing steps for the Model Optimizer highlighting the two necessary custom layer extensions, the Custom Layer Extractor and the Custom Layer Operation.
+
+![](img/MO_extensions_flow.png)
+
+
+The Model Optimizer first extracts information from the input model which includes the topology of the model layers along with parameters, input and output format, etc., for each layer.  The model is then optimized from the various known characteristics of the layers, interconnects, and data flow which partly comes from the layer operation providing details including the shape of the output for each layer.  Finally, the optimized model is output to the model IR files needed by the Inference Engine to run the model.  
+
+The Model Optimizer starts with a library of known extractors and operations for each [supported model framework](https://docs.openvinotoolkit.org/2019_R1.1/_docs_MO_DG_prepare_model_Supported_Frameworks_Layers.html) which must be extended to use each unknown custom layer.  The custom layer extensions needed by the Model Optimizer are:
+
+- Custom Layer Extractor
+   - Responsible for identifying the custom layer operation and extracting the parameters for each instance of the custom layer.  The layer parameters are stored per instance and used by the layer operation before finally appearing in the output IR.  Typically the input layer parameters are unchanged, which is the case covered by this tutorial. 
+- Custom Layer Operation
+   - Responsible for specifying the attributes that are supported by the custom layer and computing the output shape for each instance of the custom layer from its parameters. <br> The `--mo-op` command-line argument shown in the examples below generates a custom layer operation for the Model Optimizer. 
+
+## Custom Layer Extensions for the Inference Engine 
+
+The following figure shows the basic flow for the Inference Engine highlighting two custom layer extensions for the CPU and GPU Plugins, the Custom Layer CPU extension and the Custom Layer GPU Extension.
+
+![](img/IE_extensions_flow.png)
+
+Each device plugin includes a library of optimized implementations to execute known layer operations which must be extended to execute a custom layer.  The custom layer extension is implemented according to the target device:
+
+- Custom Layer CPU Extension
+   - A compiled shared library (.so or .dll binary) needed by the CPU Plugin for executing the custom layer on the CPU.  
+- Custom Layer GPU Extension
+   - OpenCL source code (.cl) for the custom layer kernel that will be compiled to execute on the GPU along with a layer description file (.xml) needed by the GPU Plugin for the custom layer kernel. 
+
+## Model Extension Generator
+
+Using answers to interactive questions or a *.json* configuration file, the Model Extension Generator tool generates template source code files for each of the extensions needed by the Model Optimizer and the Inference Engine.  To complete the implementation of each extension, the template functions may need to be edited to fill-in details specific to the custom layer or the actual custom layer functionality itself.
+
+### Command-line
+
+The Model Extension Generator is included in the Intel® Distribution of OpenVINO™ toolkit installation and is run using the command (here with the "--help" option):
+
+```bash
+python3 /opt/intel/openvino/deployment_tools/tools/extension_generator/extgen.py new --help
+```
+
+where the output will appear similar to:
+
+```
+usage: You can use any combination of the following arguments:
+
+Arguments to configure extension generation in the interactive mode:
+
+optional arguments:
+  -h, --help            show this help message and exit
+  --mo-caffe-ext        generate a Model Optimizer Caffe* extractor
+  --mo-mxnet-ext        generate a Model Optimizer MXNet* extractor
+  --mo-tf-ext           generate a Model Optimizer TensorFlow* extractor
+  --mo-op               generate a Model Optimizer operation
+  --ie-cpu-ext          generate an Inference Engine CPU extension
+  --ie-gpu-ext          generate an Inference Engine GPU extension
+  --output_dir OUTPUT_DIR
+                        set an output directory. If not specified, the current
+                        directory is used by default.
+```
+
+The available command-line arguments are used to specify which extension(s) to generate templates for the Model Optimizer or Inference Engine.  The generated extension files for each argument will appear starting from the top of the output directory as follows:
+
+Command-line Argument | Output Directory Location      |
+--------------------- | ------------------------------ |
+`--mo-caffe-ext`        | user_mo_extensions/front/caffe |
+`--mo-mxnet-ext`       | user_mo_extensions/front/mxnet |
+`--mo-tf-ext`           | user_mo_extensions/front/tf    |
+`--mo-op`               | user_mo_extensions/ops         |
+`--ie-cpu-ext`          | user_ie_extensions/cpu         |
+`--ie-gpu-ext`          | user_ie_extensions/gpu         |
+
+### Extension Workflow
+
+The workflow for each generated extension follows the same basic steps:
+
+![](img/MEG_generic_flow.png)
+
+**Step 1: Generate:** Use the Model Extension Generator to generate the Custom Layer Template Files. 
+
+**Step 2:  Edit:** Edit the Custom Layer Template Files as necessary to create the specialized Custom Layer Extension Source Code.
+
+**Step 3:  Specify:** Specify the custom layer extension locations to be used by the Model Optimizer or Inference Engine.
+
+## Caffe\* Models with Custom Layers <a name="caffe-models-with-custom-layers"></a>
+
+If your Caffe\* model has custom layers:
+
+**Register the custom layers as extensions to the Model Optimizer**. For instructions, see [Extending Model Optimizer with New Primitives](../MO_DG/prepare_model/customize_model_optimizer/Extending_Model_Optimizer_with_New_Primitives.md). When your custom layers are registered as extensions, the Model Optimizer generates a valid and optimized Intermediate Representation. You will need a bit of Python\* code that lets the Model Optimizer;
+
+- Generate a valid Intermediate Representation according to the rules you specified.
+- Be independent from the availability of Caffe on your computer.
+	
+If your model contains Custom Layers, it is important to understand the internal workflow of the Model Optimizer. Consider the following example.
+
+**Example**:
+
+The network has:
+
+*   One input layer (#1)
+*   One output Layer (#5)
+*   Three internal layers (#2, 3, 4)
+
+The custom and standard layer types are:
+
+*   Layers #2 and #5 are implemented as Model Optimizer extensions.
+*   Layers #1 and #4 are supported in Model Optimizer out-of-the box.
+*   Layer #3 is neither in the list of supported layers nor in extensions, but is specified in CustomLayersMapping.xml.
+
+> **NOTE**: If any of the layers are not in one of three categories described above, the Model Optimizer fails with an appropriate message and a link to the corresponding question in [Model Optimizer FAQ](../MO_DG/prepare_model/Model_Optimizer_FAQ.md).
+
+The general process is as shown:
+
+![Example custom layer network](img/mo_caffe_priorities.png)
+<br>
+
+**Step 1:**  The example model is fed to the Model Optimizer that **loads the model** with the special parser built on top of the `caffe.proto` file. In case of failure, the Model Optimizer asks you to prepare the parser that can read the model. For more information, refer to the Model Optimizer, <a href="MO_FAQ.html#FAQ1">FAQ #1</a>.
+
+**Step 2:**  The Model Optimizer **extracts the attributes of all layers** by going through the list of layers and attempting to find the appropriate extractor. In order of priority, the Model Optimizer checks if the layer is:
+    
+*   A.  Registered as a Model Optimizer extension
+*   B.  Registered as a standard Model Optimizer layer
+    
+When the Model Optimizer finds a satisfying condition from the list above, it extracts the attributes according to the following rules:
+    
+*   For A. - takes only the parameters specified in the extension
+*   For B. - takes only the parameters specified in the standard extractor
+<br> 
+
+**Step 3:**  The Model Optimizer **calculates the output shape of all layers**. The logic is the same as it is for the priorities. **Important:** the Model Optimizer always takes the first available option.
+
+**Step 4:**  The Model Optimizer **optimizes the original model and produces the two Intermediate Representation (IR) files in .xml and .bin**.
+<br>
+
+## TensorFlow\* Models with Custom Layers <a name="Tensorflow-models-with-custom-layers"></a>
+
+You have two options for TensorFlow\* models with custom layers:
+<br>
+
+*   **Register those layers as extensions to the Model Optimizer.** In this case, the Model Optimizer generates a valid and optimized Intermediate Representation.
+*   **If you have sub-graphs that should not be expressed with the analogous sub-graph in the Intermediate Representation, but another sub-graph should appear in the model, the Model Optimizer provides such an option.** This feature is helpful for many TensorFlow models. To read more, see [Sub-graph Replacement in the Model Optimizer](../MO_DG/prepare_model/customize_model_optimizer/Subgraph_Replacement_Model_Optimizer.md).
+	
+## MXNet\* Models with Custom Layers <a name="mxnet-models-with-custom-layers"></a>
+
+There are two options to convert your MXNet* model that contains custom layers:
+
+1.  Register the custom layers as extensions to the Model Optimizer. For instructions, see [Extending MXNet Model Optimizer with New Primitives](../MO_DG/prepare_model/customize_model_optimizer/Extending_MXNet_Model_Optimizer_with_New_Primitives.md). When your custom layers are registered as extensions, the Model Optimizer generates a valid and optimized Intermediate Representation. You can create Model Optimizer extensions for both MXNet layers with op `Custom` and layers which are not standard MXNet layers.
+
+2.  If you have sub-graphs that should not be expressed with the analogous sub-graph in the Intermediate Representation, but another sub-graph should appear in the model, the Model Optimizer provides such an option. In MXNet the function is actively used for ssd models provides an opportunity to  for the necessary subgraph sequences and replace them. To read more, see [Sub-graph Replacement in the Model Optimizer](../MO_DG/prepare_model/customize_model_optimizer/Subgraph_Replacement_Model_Optimizer.md).

+# Regression tests howto {#openvino_docs_HOWTO_add_regression_test_vpu}
+
+## Purpose
+
+This document contains instructions for correctly modifying a set of regression tests.
+
+## Common
+
+Regression tests for Myriad and HDDL plugins are on the path:
+`inference-engine/tests/functional/vpu/regression_tests/`
+
+The tests are divided into 4 groups:
+* Classification
+* Detection
+* Raw-results
+* Compilation
+* VPU hetero
+
+Testing  framework – [Google Test](https://github.com/google/googletest/).
+Each group contains [parameterized](https://github.com/google/googletest/blob/master/googletest/docs/advanced.md) tests. The main idea is that to add a new test, you only need to add a new parameter. Except for scenarios different from the generalized case.
+
+## Classsification and Detection tests
+
+These groups contains two cases:
+
+* For generalized scenario (` VpuNoClassificationRegression, VpuNoDetectionRegression`)
+* For specific scenario (` VpuNoClassificationRegressionSpecific, VpuNoDetectionRegressionSpecific`)
+
+### Generalized scenario
+
+If You want test new parameter(batch, precision, model and etc.) then You need to edit the existing initialization of parameterized tests or create a new one.  
+Example of initialization of parameterized tests:
+
+``` c++
+INSTANTIATE_TEST_CASE_P(
+        VPURegTestWithResources_nightly,
+        VpuNoClassificationRegression,
+        Combine(ValuesIn(VpuTestParamsContainer::testingPlugin()),
+                Values(Precision::FP16),
+                Values(1),  // batches
+                Values(true), //IsHwAdaptiveMode
+                Values(false), //DoReshape
+                Values(3, 5, 7), //Resources
+                Values(false), //IsIgnoreStatistic
+                Values(ClassificationSrcParam{ModelName::GoogleNetV1, SourceImages::kCat3, 0.01, Regression::EMean::eValues})),
+        VpuNoClassificationRegression::getTestCaseName);
+```
+
+### Specific scenario
+
+If You need a test to perform some actions that are not provided in the generalized scenario, then add a specific test case. As with the generalized scenario You can change parameters for these tests.  
+Example of specific test case:
+
+``` c++
+TEST_P(VpuNoClassificationRegressionSpecific, onAlexNetWithNetworkConfig) {
+    DISABLE_ON_WINDOWS_IF(HDDL_PLUGIN);
+    DISABLE_IF(do_reshape_);
+
+    if (!hw_adaptive_mode_) {
+        config_[VPU_CONFIG_KEY(NETWORK_CONFIG)] = "data=data,scale=1";
+    }
+
+    assertThat().classificationResultsForInferRequestAPI()
+            .on(SourceImages::kDog2)
+            .withInputPrecision(in_precision_)
+            .times(batch_)
+            .withBatch(batch_)
+            .onModel(ModelName::AlexNet)
+            .setMean(Regression::EMean::eImage)
+            .onFP16()
+            .withTopK(1)
+            .withPluginConfig(config_)
+            .equalToReferenceWithDelta(0.04);
+}
+```
+
+## Raw-results tests
+
+There is no generalized scenario and recommendations are the same as for specific test cases for Classification/Detection groups.
+
+## Compilation tests
+
+The tests are in the `vpu_classification_regression.cpp` file and contains only one scenario ` VpuNoRegressionWithCompilation `. To add a new test just update parameters just as in generalized scenarion of Classification/Detection test groups.

+# Fuzzing howto {#openvino_docs_HOWTO_fuzzing_HOWTO}
+
+## Intended Audience
+
+This document is for a developer who wants to contribute fuzz tests.
+
+## Purpose
+
+This document walks you through creating your first fuzzer, running it and evaluating its quality.
+
+## Prerequisites
+
+- Linux OS or Mac OS.
+
+- [American Fuzzy Loop](http://lcamtuf.coredump.cx/afl/) if building   with GCC.
+
+## Steps
+
+1. Create a fuzz test in the existing project at `./tests/fuzz`. Fuzz test must
+   follow `<test name>-fuzzer.cc` naming scheme and implement a
+   `LLVMFuzzerTestOneInput` entry point.
+
+``` bash
+cat << EOF > ./tests/fuzz/test_name-fuzzer.cc
+#include <stdint.h>
+#include <cstdlib>
+
+extern "C" int LLVMFuzzerTestOneInput(const uint8_t* data, size_t size) {
+  // put your fuzzing code here and use data+size as input.
+  return 0;  // always return 0
+}
+EOF
+```
+
+2. Implement test logic under `LLVMFuzzerTestOneInput`.
+
+See example fuzz test at `tests/fuzz/read_network-fuzzer.cc`.
+
+3. Build fuzz tests with `-DENABLE_FUZZING=ON` flag for cmake.
+
+``` bash
+    mkdir -p build && \
+    (cd build && \
+    CXX=afl-g++ CC=afl-gcc cmake -DCMAKE_BUILD_TYPE=Debug -DENABLE_FUZZING=ON -DENABLE_TESTS=ON .. && \
+    make fuzz --jobs=$(getconf _NPROCESSORS_ONLN))
+```
+
+4. Prepare sample inputs for your fuzz test to teach fuzzer engine on input
+   structure
+
+``` bash
+(cd bin/intel64/Debug && \
+mkdir test_name-corpus && \
+echo sample input > test_name-corpus/in1.txt)
+```
+
+5. Evaluate fuzz test with `afl-fuzz` fuzzing engine
+
+Run fuzz test:
+
+``` bash
+(cd bin/intel64/Debug && \
+afl-fuzz -i test_name-corpus -o test_name-out -- ./test_name-fuzzer @@
+```
+
+While fuzz test is running it prints out statistics. Besides just crashes `uniq
+crashes` and hangs `uniq hangs` you should care about fuzz test quality:
+
+- Fuzz test should be fast - speed of execution `exec speed` should be at least
+  100 exec/s. Speed less than 20 exec/s is not acceptable.
+
+- Fuzz test should be able to explore new code paths `map coverage` and
+  `findings in depth`. Confirm it is increasing while fuzz test is running.
+
+6. Reproduce fuzz test findings
+
+All issues found by fuzz test are stored as a file in output folder specified
+earlier via `-o` afl-fuzz option. To reproduce an issue run fuzz test executable
+with an issue file as an argument.
+
+## Summary
+
+We have created a simple fuzz test, run it and asses its results.
+
+## Extension
+
+Try run parallel fuzzing with the help of
+[afl-utils](https://gitlab.com/rc0r/afl-utils).
+
+## Tips or FAQs
+
+GCC 7 in Ubuntu 18.04 LTS has a
+[defect](https://bugs.launchpad.net/ubuntu/+source/afl/+bug/1774816). Upgrade
+GCC 7 for AFL to work. GCC version `Ubuntu 7.3.0-27ubuntu1~18.04` works OK.

+# Bfloat16 Inference {#openvino_docs_IE_DG_Bfloat16Inference}
+
+## Disclaimer
+
+Inference Engine with the bfloat16 inference implemented on CPU must support the `avx512_bf16` instruction and therefore the bfloat16 data format.
+
+## Introduction
+
+Bfloat16 computations (referred to as BF16) is the Brain Floating-Point format with 16 bits. This is a truncated 16-bit version of the 32-bit IEEE 754 single-precision floating-point format FP32. BF16 preserves 8 exponent bits as FP32 but reduces precision of the sign and mantissa from 24 bits to 8 bits.
+
+![bf16_format]
+
+Preserving the exponent bits keeps BF16 to the same range as the FP32 (~1e-38 to ~3e38). This simplifies conversion between two data types: you just need to skip or flush to zero 16 low bits.
+Truncated mantissa leads to occasionally less precision, but according to [investigations](https://cloud.google.com/blog/products/ai-machine-learning/bfloat16-the-secret-to-high-performance-on-cloud-tpus), neural networks are more sensitive to the size of the exponent than the mantissa size. Also, in lots of models, precision is needed close to zero but not so much at the maximum range.
+Another useful feature of BF16 is possibility to encode an INT8 in BF16 without loss of accuracy, because INT8 range completely fits in BF16 mantissa field. It reduces data flow in conversion from INT8 input image data to BF16 directly without intermediate representation in FP32, or in combination of [INT8 inference](Int8Inference.md) and BF16 layers.
+
+See the [Intel's site](https://software.intel.com/sites/default/files/managed/40/8b/bf16-hardware-numerics-definition-white-paper.pdf) for more bfloat16 format details.
+
+There are two ways to check if CPU device can support bfloat16 computations for models:
+1. Query the instruction set via system `lscpu | grep avx512_bf16` or `cat /proc/cpuinfo | grep avx512_bf16`.
+2. Use [Query API](InferenceEngine_QueryAPI.md) with `METRIC_KEY(OPTIMIZATION_CAPABILITIES)`, which should return `BF16` in the list of CPU optimization options:
+
+```cpp
+InferenceEngine::Core core;
+auto cpuOptimizationCapabilities = core.GetMetric("CPU", METRIC_KEY(OPTIMIZATION_CAPABILITIES)).as<std::vector<std::string>>();
+```
+
+Current Inference Engine solution for bfloat16 inference uses Intel® Math Kernel Library for Deep Neural Networks (Intel® MKL-DNN) and supports inference of the following layers in BF16 computation mode:
+* Convolution
+* FullyConnected
+* InnerProduct
+* LRN
+* Pooling
+
+This means that BF16 inference can only be performed with the CPU plugin on the layers listed above. All other layers are executed in FP32.
+
+## Lowering Inference Precision
+
+Lowering precision to increase performance is [widely used](https://software.intel.com/content/www/us/en/develop/articles/lower-numerical-precision-deep-learning-inference-and-training.html) for optimization of inference. The bfloat16 data type usage on CPU for the first time opens the possibility of default optimization approach.
+The embodiment of this approach is to use the optimization capabilities of the current platform to achieve maximum performance while maintaining the accuracy of calculations within the acceptable range.
+
+Bfloat16 data usage provides the following benefits that increase performance:
+1. Faster multiplication of two BF16 numbers because of shorter mantissa of bfloat16 data.
+2. No need to support denormals and handling exceptions as this is a performance optimization.
+3. Fast conversion of float32 to bfloat16 and vice versa.
+4. Reduced size of data in memory, as a result, larger models fit in the same memory bounds.
+5. Reduced amount of data that must be transferred, as a result, reduced data transition time.
+
+For default optimization on CPU, source model converts from FP32 or FP16 to BF16 and executes internally on platforms with native BF16 support. In that case, `KEY_ENFORCE_BF16` is set to `YES`.
+The code below demonstrates how to check if the key is set:
+
+```cpp
+InferenceEngine::Core core;
+auto exeNetwork = core.LoadNetwork(network, "CPU");
+auto enforceBF16 = exeNetwork.GetConfig(PluginConfigParams::KEY_ENFORCE_BF16).as<std::string>();
+```
+
+To disable BF16 internal transformations, set the `KEY_ENFORCE_BF16` to `NO`. In this case, the model infers AS IS without modifications with precisions that were set on each layer edge.
+
+```cpp
+InferenceEngine::Core core;
+core.SetConfig({ { CONFIG_KEY(ENFORCE_BF16), CONFIG_VALUE(NO) } }, "CPU");
+```
+
+An exception with message `Platform doesn't support BF16 format` is formed in case of setting `KEY_ENFORCE_BF16` to `YES` on CPU without native BF16 support.
+
+Low-Precision 8-bit integer models do not convert to BF16, even if bfloat16 optimization is set by default.         
+
+## Performance Counters
+
+Information about layer precision is stored in the performance counters that are
+available from the Inference Engine API. The layers have the following marks:
+* Suffix `BF16` for layers that had bfloat16 data type input and were computed in BF16 precision
+* Suffix `FP32` for layers computed in 32-bit precision
+
+For example, the performance counters table for the Inception model can look as follows:
+
+```
+pool5                         EXECUTED       layerType: Pooling            realTime: 143       cpu: 143             execType: jit_avx512_BF16

+fc7                           EXECUTED       layerType: FullyConnected     realTime: 7558      cpu: 7558            execType: jit_gemm_BF16
+relu7                         NOT_RUN        layerType: ReLU               realTime: 0         cpu: 0               execType: undef
+fc8                           EXECUTED       layerType: FullyConnected     realTime: 2193      cpu: 2193            execType: jit_gemm_BF16
+prob                          EXECUTED       layerType: SoftMax            realTime: 68        cpu: 68              execType: jit_avx512_FP32
+```
+
+The `execType` column of the table includes inference primitives with specific suffixes.

+Cross Check Tool {#openvino_docs_IE_DG_Cross_Check_Tool}
+================
+
+Cross Check Tool is a console application that enables comparing accuracy and performance metrics for two successive
+model inferences that are performed
+on two different supported Intel® devices or with different precisions.
+The Cross Check Tool can compare metrics per layer or all over the model.
+
+On Linux* OS, before running the Cross Check Tool binary, make sure your application can find the
+Deep Learning Inference Engine libraries.
+Navigate to the `<INSTALL_DIR>/deployment_tools/inference_engine/bin` folder and run the `setvars.sh` script to
+set all necessary environment variables:
+
+```sh
+source setvars.sh
+```
+
+## Running the Cross Check Tool
+
+Cross Check Tool is distributed as a binary file and there is no need to build it. To run the Cross Check Tool,
+execute the tool's binary file with necessary parameters. Please note that the Inference Engine assumes that weights
+are in the same folder as the _.xml_ file.
+
+You can get the list of all available options using the -h option:
+
+```sh
+$./cross_check_tool -h
+InferenceEngine:
+  API version ............ 1.0
+  Build .................. ###
+[ INFO ] Parsing input parameters
+

+
+## Introduction to the OpenVINO™ Toolkit
+
+The OpenVINO™ toolkit is a comprehensive toolkit that you can use to develop and deploy vision-oriented solutions on
+Intel® platforms. Vision-oriented means the solutions use images or videos to perform specific tasks.
+A few of the solutions use cases include autonomous navigation, digital surveillance cameras, robotics,
+and mixed-reality headsets.
+
+The OpenVINO™ toolkit:
+
+* Enables CNN-based deep learning inference on the edge
+* Supports heterogeneous execution across an Intel® CPU, Intel® Integrated Graphics, Intel® Movidius™ Neural Compute Stick and Intel® Neural Compute Stick 2
+* Speeds time-to-market via an easy-to-use library of computer vision functions and pre-optimized kernels
+* Includes optimized calls for computer vision standards including OpenCV\*, OpenCL™, and OpenVX\*
+
+The OpenVINO™ toolkit includes the following components:
+
+* Intel® Deep Learning Deployment Toolkit (Intel® DLDT)
+    - [Deep Learning Model Optimizer](../MO_DG/Deep_Learning_Model_Optimizer_DevGuide.md) — A cross-platform command-line tool for importing models and
+    preparing them for optimal execution with the Deep Learning Inference Engine. The Model Optimizer supports converting Caffe*,
+    TensorFlow*, MXNet*, Kaldi*, ONNX* models.
+    - [Deep Learning Inference Engine](inference_engine_intro.md) — A unified API to allow high performance inference on many hardware types
+    including Intel® CPU, Intel® Processor Graphics, Intel® FPGA, Intel® Neural Compute Stick 2.
+    - [nGraph](nGraph_Flow.md) — graph representation and manipulation engine which is used to represent a model inside Inference Engine and allows the run-time model construction without using Model Optimizer.
+* [OpenCV](https://docs.opencv.org/) — OpenCV* community version compiled for Intel® hardware.
+Includes PVL libraries for computer vision.
+* Drivers and runtimes for OpenCL™ version 2.1
+* [Intel® Media SDK](https://software.intel.com/en-us/media-sdk)

+Using Dynamic Batching {#openvino_docs_IE_DG_DynamicBatching}
+======================
+
+Dynamic Batching feature allows you+ to dynamically change batch size for inference calls
+within preset batch size limit.
+This feature might be useful when batch size is unknown beforehand, and using extra large batch size is
+undesired or impossible due to resource limitations.
+For example, face detection with person age, gender, or mood recognition is a typical usage scenario.
+
+
+## Usage
+
+You can activate Dynamic Batching by setting <code>KEY_DYN_BATCH_ENABLED</code> flag to <code>YES</code> in a configuration map that is
+passed to the plugin while loading a network.
+This configuration creates an <code>ExecutableNetwork</code> object that will allow setting batch size
+dynamically in all of its infer requests using <code>SetBatch()</code> method.
+The batch size that was set in passed <code>CNNNetwork</code> object will be used as a maximum batch size limit.
+
+Here is a code example:
+```cpp
+int dynBatchLimit = FLAGS_bl;	//take dynamic batch limit from command line option
+
+// Read network model
+Core core;
+CNNNetwork network = core.ReadNetwork(modelFileName, weightFileName);
+
+// enable dynamic batching and prepare for setting max batch limit
+const std::map<std::string, std::string> dyn_config = 
+{ { PluginConfigParams::KEY_DYN_BATCH_ENABLED, PluginConfigParams::YES } };
+network.setBatchSize(dynBatchLimit);
+
+// create executable network and infer request
+auto executable_network = core.LoadNetwork(network, "CPU", dyn_config);
+auto infer_request = executable_network.CreateInferRequest();
+
+
+...
+
+
+// process a set of images
+// dynamically set batch size for subsequent Infer() calls of this request
+size_t batchSize = imagesData.size();
+infer_request.SetBatch(batchSize);
+infer_request.Infer();
+
+...
+
+// process another set of images
+batchSize = imagesData2.size();
+infer_request.SetBatch(batchSize);
+infer_request.Infer();
+```
+
+
+## Limitations
+
+Currently, certain limitations for using Dynamic Batching exist:
+
+* Use Dynamic Batching with CPU and GPU plugins only.
+
+* Use Dynamic Batching on topologies that consist of certain layers only:
+
+	* Convolution
+	* Deconvolution
+	* Activation
+	* LRN
+	* Pooling
+	* FullyConnected
+	* SoftMax
+	* Split
+	* Concatenation
+	* Power
+	* Eltwise
+	* Crop
+	* BatchNormalization
+	* Copy
+	
+Do not use layers that might arbitrary change tensor shape (such as Flatten, Permute, Reshape),
+layers specific to object detection topologies (ROIPooling, ProirBox, DetectionOutput), and
+custom layers.
+Topology analysis is performed during the process of loading a network into plugin, and if topology is
+not applicable, an exception is generated.

+# Add Custom nGraph Operations {#openvino_docs_IE_DG_Extensibility_DG_AddingNGraphOps}
+
+Inference Engine Extension API allows to register operation sets (opsets) with custom nGraph operations, it allows to support Networks with unknown operations.
+
+## Operation Class
+
+To add your custom nGraph operation, create a new class that extends `ngraph::Op`, which is in turn derived from `ngraph::Node`, the base class for all graph operations in nGraph. Follow the steps below:
+
+1. Define a `NodeTypeInfo` object that identifies the type of the operation to the graph users and helps with dynamic type resolution. The type info of an nGraph operation currently consists of a string identifier and a version number, but this may change in the future.
+
+2. Implement constructors that can optionally take the operation inputs and attributes as parameters. 
+
+3. Override the shape inference method `validate_and_infer_types`. This method is called multiple times during graph manipulations to determine the shapes and element types of the outputs of the operations. You can access the input shapes through the `get_input_partial_shape()` method and input element types through the `get_input_element_type()` method of `ngraph::Node`. Set the inferred shape and element type of the output using `set_output_type`.
+
+4. Override the `copy_with_new_args` method, which allows graph manipulation routines to create copies of this operation and connect it to different nodes during optimization.
+
+5. Override the `visit_attributes` method, which allows serialization and deserialization of attributes. An `AttributeVisitor` is passed to the method, and the implementation is expected to walk over all the attributes in the op using the type-aware `on_attribute` helper. Helpers are already implemented for standard C++ types like `int64_t`, `float`, `bool`, `vector` and for existing nGraph defined types.
+
+Based on that, declaration of a operation class can look as follows:
+
+@snippet op.hpp op:header
+
+### Class Fields
+
+The provided implementation has several fields:
+
+ * `add` of type `int64_t` is an attribute of custom operation
+ * `type_info` of type `ngraph::NodeTypeInfo` defines the type and version of operation
+
+### Operation Constructors
+
+nGraph operation contains two constructors: a default constructor, which allows to create operation without attributes and a constructor that creates and validates operation with specified inputs and attributes.
+
+@snippet op.cpp op:ctor
+
+### `validate_and_infer_types()`
+
+`ngraph::Node::validate_and_infer_types` method validates operation attributes and calculates output shapes using attributes of operation.
+
+@snippet op.cpp op:validate
+
+### `copy_with_new_args()`
+
+`ngraph::Node::copy_with_new_args` method creates a copy of nGraph operation with new inputs.
+
+@snippet op.cpp op:copy
+
+### `visit_attributes()`
+
+`ngraph::Node::visit_attributes` method allows to visit all operation attributes.
+
+@snippet op.cpp op:visit_attributes
+
+## Register Custom Operations in Extension Class
+
+To add custom operations to the [Extension](Extension.md) class, create an operation set with custom operations and implement the `InferenceEngine::IExtension::getOpSets` method:
+
+@snippet extension.cpp extension:getOpSets
+
+This method returns a map of opsets that exist in the extension library.
+
+nGraph provides opsets mechanism for operation versioning. Different opsets distinguish between different versions of one operation.
+
+When specifying opset names, follow the rules below:
+* Use unique opset names.
+* Do not use the following built-in opset names: `extension`, `experimental`, `opset1`, `opest2`.
+* Make sure that the Model Optimizer and your extension use the same opset names.
+* IR v10 layers have the mandatory `version` attribute  specifying the opset. 
+* `opset1` is the name of default operations set.
+Operations from the default opset cannot be redefined.
+
+Use a custom opset to create a new operation or extend functionality of an existing operation from another opset.

+# How to Implement Custom CPU Layers {#openvino_docs_IE_DG_Extensibility_DG_CPU_Kernel}
+
+The primary vehicle for the performance of the CPU codepath in the Inference Engine is the Intel® Math Kernel Library for Deep Neural Networks (Intel® MKL-DNN), and new CPU kernels extend the Inference Engine plugin for the Intel MKL-DNN. Implementing the InferenceEngine::ILayerExecImpl defines a general CPU-side extension. There are no Intel MKL-DNN specifics in the way you need to implement a kernel.
+
+## Implementation Class
+
+All custom kernels for the CPU plugin should be inherited from the InferenceEngine::ILayerExecImpl interface.
+Based on that, declaration of a kernel implementation class can look as follows:
+
+@snippet cpu_kernel.hpp cpu_implementation:header
+
+### Class Fields
+
+The provided implementation has several fields:
+
+ * `add` of the type `int64_t` is an attribute of a custom operation
+ * `inShape` of the type `ngraph::Shape` is an input shape
+ * `outShape` of the type `ngraph::Shape` is an output shape
+ * `error` of the type `std::string` is a field to handle errors from a constructor
+
+### Constructor of Implementation
+
+An implementation constructor checks parameters of nGraph operation, stores needed attributes, and stores an error message in the case of an error.
+
+@snippet cpu_kernel.cpp cpu_implementation:ctor
+
+### `getSupportedConfigurations`
+
+InferenceEngine::ILayerExecImpl::getSupportedConfigurations method returns all supported configuration formats (input/output tensor layouts) for your implementation. To specify formats of data, use InferenceEngine::TensorDesc. Refer to the [Memory Primitives](../Memory_primitives.md) section for instructions on how to do it.
+
+@snippet cpu_kernel.cpp cpu_implementation:getSupportedConfigurations
+
+### `init`
+
+InferenceEngine::ILayerExecImpl::init method gets a runtime-selected configuration from a vector that is populated from the `getSupportedConfigurations` method and checks the parameters:
+
+@snippet cpu_kernel.cpp cpu_implementation:init
+
+### `execute`
+
+InferenceEngine::ILayerExecImpl::execute method accepts and processes the actual tenors as input/output blobs:
+
+@snippet cpu_kernel.cpp cpu_implementation:execute
+
+## Register Implementation in `Extension` Class
+
+To register custom kernel implementation in the [Extension](Extension.md) class, implement the following methods:
+* <a href="#getImpTypes">getImplTypes</a>
+* <a href="#getImplementation">getImplementation</a>
+
+### <a name="getImpTypes"><code>getImplTypes</code></a>
+
+InferenceEngine::IExtension::getImplTypes returns a vector of implementation types for an operation.
+
+@snippet extension.cpp extension:getImplTypes
+
+### <a name="getImplementation"><code>getImplementation</code></a>
+
+InferenceEngine::IExtension::getImplementation returns the kernel implementation with a specified type for an operation.
+
+@snippet extension.cpp extension:getImplementation
+
+
+## Load Extension with Executable Kernels to Plugin
+
+Use the `AddExtension` method of the general plugin interface to load your primitives:
+```cpp
+InferenceEngine::Core core;
+// Load CPU extension as a shared library
+auto extension_ptr = make_so_pointer<InferenceEngine::IExtension>("<shared lib path>");
+// Add extension to the CPU device

+Inference Engine provides an InferenceEngine::IExtension interface, which defines the interface for Inference Engine Extension libraries.
+All extension libraries should be inherited from this interface.
+
+Based on that, declaration of an extension class can look as follows:

+# How to Implement Custom GPU Layers {#openvino_docs_IE_DG_Extensibility_DG_GPU_Kernel}
+
+The GPU codepath abstracts many details about OpenCL™. You need to provide the kernel code in OpenCL C and the configuration file that connects the kernel and its parameters to the parameters of the layer.
+
+There are two options of using custom layer configuration file:
+
+* Include a section with your kernels into the global automatically-loaded `cldnn_global_custom_kernels/cldnn_global_custom_kernels.xml` file, which is hosted in the `<INSTALL_DIR>/deployment_tools/inference_engine/bin/intel64/{Debug/Release}` folder
+* Call the `InferenceEngine::Core::SetConfig()` method from your application with the `InferenceEngine::PluginConfigParams::KEY_CONFIG_FILE` key and the configuration file name as a value before loading the network that uses custom layers to the plugin:
+```cpp
+InferenceEngine::Core core;
+// Load GPU Extensions
+core.SetConfig({ { InferenceEngine::PluginConfigParams::KEY_CONFIG_FILE, "<path_to_the_xml_file>" } }, "GPU");
+```
+
+All Inference Engine samples, except trivial `hello_classification`,
+feature a dedicated command-line option `-c` to load custom kernels. For example, to load custom layers for the classification sample, run the command below:
+```sh
+$ ./classification_sample -m <path_to_model>/bvlc_alexnet_fp16.xml -i ./validation_set/daily/227x227/apron.bmp -d GPU
+ -c <absolute_path_to_config>/custom_layer_example.xml
+```
+
+## Configuration File Format <a name="config-file-format"></a>
+
+The configuration file is expected to follow the `.xml` file structure
+with a node of the type `CustomLayer` for every custom layer you provide.
+
+The definitions described in the sections below use the following notations:
+
+Notation | Description
+---|---
+(0/1) | Can have 0 or 1 instances of this node/attribute
+(1) | Must have only 1 instance of this node/attribute

+
+## Built-In Defines for Custom Layers
+
+The following table includes definitions that are attached before

+| `<TENSOR>_FORMAT_` | The format of the tensor, BFYX, BYXF, YXFB , FYXB, or ANY. The format is concatenated to the defined name. You can use the tensor format to define codepaths in your code with `#&zwj;ifdef/#&zwj;endif`. |
+| `<TENSOR>_LOWER_PADDING` | An array of padding elements used for the tensor dimensions before they start. Always ordered as BFYX.|
+| `<TENSOR>_ LOWER_PADDING_SIZE` | The size of the `<TENSOR>_LOWER_PADDING` array  |

+
+## Debugging Tips<a name="debugging-tips"></a>
+
+* **Dumping the Resulting Kernels**.
+It is recommended to get a dump of the kernel with all of
+the values set by the Inference Engine, such as tensor sizes,
+floating-point, and integer kernel parameters. To get the dump, add the
+following line to your code that configures the GPU plugin to output the
+custom kernels:
+```cpp
+core.SetConfig({ { PluginConfigParams::KEY_DUMP_KERNELS, PluginConfigParams::YES } }, "GPU");
+```
+When the Inference Engine compiles the kernels for the specific network,
+it also outputs the resulting code for the custom kernels. In the
+directory of your executable, find files like
+`clDNN_program0.cl`, `clDNN_program1.cl`. There are as many files as
+distinct sets of parameters for your custom kernel: different input
+tensor sizes and kernel parameters.
+
+* **Using `printf` in the OpenCL™ Kernels**.
+To debug the specific values, you can use `printf` in your kernels.
+However, be careful: for instance, do not output excessively
+as it would generate too much data. The `printf` output is typical, so
+your output can be truncated to fit the buffer. Also, because of
+buffering, you actually get an entire buffer of output when the
+execution ends.<br>
+For more information, refer to the [printf
+Function](https://www.khronos.org/registry/OpenCL/sdk/1.2/docs/man/xhtml/printfFunction.html).

+# Inference Engine Extensibility Mechanism {#openvino_docs_IE_DG_Extensibility_DG_Intro}
+
+Inference Engine Extensibility API allows to add support of custom operations to the Inference Engine.
+Extension should contain operation sets with custom operations and execution kernels for custom operations.
+Physically, an extension library can be represented as a dynamic library exporting the single `CreateExtension` function that allows to create a new extension instance.
+
+Extensibility library can be loaded to the InferenceEngine::Core object using the InferenceEngine::Core::AddExtension method.
+
+## Inference Engine Extension Library
+
+Inference Engine Extension dynamic library contains several main components:
+
+ * [Extension class](Extension.md):
+    - Contains custom operation sets
+    - Provides CPU implementations for custom operations
+ * [Custom operations](Intro.md):
+    - Allows to use InferenceEngine::Core::ReadNetwork to read Intermediate Representation (IR) with unsupported operations 
+    - Allows to create `ngraph::Function` with unsupported operations
+    - Provides shape inference mechanism for custom operations
+
+> **NOTE**: This documentation is written based on the `Template extension`, which demonstrates extension 
+development details. Find the complete code of the `Template extension`, which is fully compilable and up-to-date,
+at `<dldt source tree>/docs/template_extension`.
+
+## Execution Kernels
+
+The Inference Engine workflow involves the creation of custom kernels and either custom or existing operations.
+
+An _Operation_ is a Network building block implemented in the training framework, for example, `Convolution` in Caffe*.
+A _Kernel_ is defined as the corresponding implementation in the Inference Engine.
+
+Refer to the [Custom Layers in the Model Optimizer](../../MO_DG/prepare_model/customize_model_optimizer/Customize_Model_Optimizer.md) section for details on how
+mapping between framework layers and Inference Engine kernels is registered.
+
+In short, you can plug your own kernel implementations into the Inference Engine and map them to the layers in the original framework.
+
+The following pages describe how to integrate custom _kernels_ into the Inference Engine:
+
+ * [Introduction to development of custom CPU kernels](CPU_Kernel.md)
+ * [Introduction to development of custom GPU kernels](GPU_Kernel.md)
+ * [Introduction to development of custom VPU kernels](VPU_Kernel.md)
+
+## Deprecated Extensibility API
+
+Shape Inference API and some methods of extensibility mechanism was deprecated and will be removed soon.
+Old Extensibility mechanism contains two parts shape inference and execution kernel.
+ * [Shape Inference](deprecated/ShapeInfer.md)
+ * [Execution Kernel](deprecated/Factory.md)

+The OpenCL™ toolchain for the Intel® Neural Compute Stick 2 supports offline compilation only, so first compile OpenCL C code using the standalone `clc` compiler. You can find the compiler binary at `<INSTALL_DIR>/deployment_tools/tools/cl_compiler`.
+
+> **NOTE:** By design, custom OpenCL layers support any OpenCL kernels written with 1.2 version assumed. It also supports half float
+extension and is optimized for this type, because it is a native type for Intel®  Movidius™ VPUs.
+
+1. Prior to running a compilation, make sure that the following variables are set:
+   * `SHAVE_MA2X8XLIBS_DIR=<INSTALL_DIR>/deployment_tools/tools/cl_compiler/lib/`
+   * `SHAVE_LDSCRIPT_DIR=<INSTALL_DIR>/deployment_tools/tools/cl_compiler/ldscripts/`
+   * `SHAVE_MYRIAD_LD_DIR=<INSTALL_DIR>/deployment_tools/tools/cl_compiler/bin/`
+   * `SHAVE_MOVIASM_DIR=<INSTALL_DIR>/deployment_tools/tools/cl_compiler/bin/`
+2. Run the compilation with the command below. You should use `--strip-binary-header` to make an OpenCL runtime-agnostic binary runnable with the Inference Engine.
+```bash
+cd <INSTALL_DIR>/deployment_tools/tools/cl_compiler/bin
+./clc --strip-binary-header custom_layer.cl -o custom_layer.bin
+```
+
+## Write a Configuration File
+
+To tie the topology IR for a layer you customize, prepare a configuration file, so that the Inference Engine can find parameters for your kernel and the execution work grid is described.
+For example, given the following OpenCL kernel signature:
+```cpp
+__kernel void reorg_nhwc(__global const half *src, __global half *out, int w, int h, int c, int stride);
+```
+Configuration file for this kernel might be the following:
+```xml
+<CustomLayer name="ReorgYolo" type="MVCL" version="1">
+   <Kernel entry="reorg_nhwc">
+       <Source filename="reorg.bin"/>
+   </Kernel>
+   <Parameters>
+       <Tensor arg-name="src"    type="input"  port-index="0"                format="BYXF"/>
+       <Tensor arg-name="out"    type="output" port-index="0"                format="BYXF"/>
+       <Scalar arg-name="w"      type="int"    port-index="0" source="I.X"                />
+       <Scalar arg-name="h"      type="int"    port-index="0" source="I.Y"                />
+       <Scalar arg-name="c"      type="int"    port-index="0" source="I.F"                />
+       <Scalar arg-name="stride" type="int"                   source="stride"             />
+   </Parameters>
+   <WorkSizes dim="input,0" global="(Y+7)/8*8,1,1" local="8,1,1"/>
+</CustomLayer>
+```
+Each custom layer is described with the `CustomLayer` node. It has the following nodes and attributes:
+  - Root node `CustomLayer` contains the following attributes:
+    - `name` – (Required) A name of the Inference Engine layer to bind the kernel with.
+    - `type` and `version` – (Required) Reserved for future use. Set them to `MVCL` and `1` respectively.
+    - `max-shaves` – (Optional) The maximum number of SHAVE cores that should be dedicated for the layer. It is useful for debugging concurrency issues or for resource saving if memory bound kernel does not scale well with the number of cores, so more resources can be left for the rest of a topology.
+  - Sub-node `Kernel` must contain the following attributes:
+    - `entry` – A name of your kernel function as you defined it in a source file (in the example above, it is `reorg_nhwc`).
+    - Node `Source` must contain the following attributes:
+      - `filename` – A path to a compiled binary relative to the `.xml` binding file.
+  - Sub-node `Parameters` – Describes parameters bindings. For more information, see the description below.
+  - Sub-node `WorkSizes` – Describes local and global work group sizes and the source for dimension deduction as a pair `direction,port`. In the example above, the work group is described relatively to the dimension of the input tensor that comes through port 0 in the IR. `global` and `local` work group configurations support any simple math expressions with +,-,\*,/, and () from `B`(batch), `Y`(height), `X`(width) and `F`(channels).
+  - Sub-node `Where` – Allows to customize bindings with the `key="value"` attribute. For example, to substitute only 3x3 convolutions, write `<Where kernel="3,3"/>` in the binging xml.
+
+  Parameter description supports `Tensor` of one of tensor types such as `input`, `output`, `input_buffer`, `output_buffer` or `data`, `Scalar`, or `Data` nodes and has the following format:
+  - Each `Tensor` node of `input` or `output` type must contain the following attributes:
+    - `arg-name` – A name of a kernel parameter in the kernel signature.
+    - `type` – Node type: `input` or `output` as in the IR.
+    - `port-index` – A number of input/output ports as in the IR.
+    - `format` – The channel order in the tensor. Optional conversion layers are generated if the custom layer format is not compatible with formats of neighboring layers. `BFXY`, `BYXF`, and `ANY` formats are supported currently.
+  - Each `Tensor` node of `input_buffer` or `output_buffer` type must contain the following attributes:
+    - `arg-name` – A name of a kernel parameter in the kernel signature.
+    - `type` – Node type: `input_buffer` or `output_buffer`. Use the appropriate type to bind multiple kernels that correspond to different stages of the same layer.
+    - `port-index` – The unique identifier to bind by.
+    - `dim` – The dim source with the same `direction,port` format used for `WorkSizes` bindings.
+    - `size` – Amount of bytes needed. Current expression syntax supports only expression over dimensions of over selected input/output tensor or constants and might be expended in the future.
+
+    Here is an example of multi-stage MVN layer binding:
+  ```xml
+  <CustomLayer name="MVN" stage="0" type="MVCL" version="1">
+      <Kernel entry="reduction_mean">
+          <Source filename="mvn.bin"/>
+      </Kernel>
+      <Parameters>
+          <Tensor arg-name="src"                type="input"         port-index="0"               format="BFYX"/>
+          <Tensor arg-name="mean"               type="output_buffer" port-index="0" dim="output,0" size="Y*F*4"/>
+          <Tensor arg-name="variance"           type="output_buffer" port-index="1" dim="output,0" size="Y*F*4"/>
+          <!--other parameters  -->
+      </Parameters>
+      <WorkSizes dim="output,0" global="((Y+7)/8)*8,F,1" local="8,1,1"/>
+  </CustomLayer>
+  <CustomLayer name="MVN" stage="1" type="MVCL" version="1">
+      <Kernel entry="mvn_scale">
+          <Source filename="mvn_scale_changed_orded.bin"/>
+      </Kernel>
+      <Parameters>
+          <Tensor arg-name="src_data"           type="input"        port-index="0"               format="BFYX"/>
+          <Tensor arg-name="dst_data"           type="output"       port-index="0"               format="BFYX"/>
+          <Tensor arg-name="mean_part"          type="input_buffer" port-index="0" dim="output,0" size="Y*F*4"/>
+          <Tensor arg-name="power_mean"         type="input_buffer" port-index="1" dim="output,0" size="Y*F*4"/>
+          <!--other parameters  -->
+      </Parameters>
+      <WorkSizes dim="output,0" global="((Y+7)/8)*8,F,1" local="8,1,1"/>
+  </CustomLayer>
+  ```
+  - Each `Tensor` node that has the type `data` must contain the following attributes:
+   - `source` – A name of the blob as it is in the IR (typical example is `weights` for convolution
+   - `format` – Specifies the channel order in the tensor. Optional conversion layers are generated if the custom layer format is not.
+  ```xml
+  <CustomLayer name="BinaryConvolution" type="MVCL" version="1">
+    <Kernel entry="binary_convolution">
+        <Source filename="binary_layers.bin"/>
+    </Kernel>
+    <Parameters>
+        <Tensor arg-name="src_data"      type="input"   port-index="0"                      format="BFYX"/>
+        <Data   arg-name="weights_data"  type="data"                     source="weights"   format="ANY"/>
+        <Tensor arg-name="dst_data"      type="output"  port-index="0"                      format="BFYX"/>
+        <!--other parameters  -->
+    </Parameters>
+    <WorkSizes dim="output,0" global="X,Y,F" local="1,1,1"/>
+  </CustomLayer>
+  ```
+  - Each `Scalar` node must contain the following attributes:
+   - `arg-name` – A name of a kernel parameter in the kernel signature.
+   - `type` – `int` or `float` value. It is used for correct argument extraction from IR parameters.
+   - `source` – Contains the name of the parameter in the IR file or input/output (`I`/`O`, `In`/`On`, where `n` is a port number)
+   followed by dimension `B`(batch), `Y`(height), `X`(width), or `F`(channels).
+
+  - Each `Data` node must contain the following attributes:
+    - `arg-name` – A name of a kernel parameter in the kernel signature.
+    - `type` – Node type. Currently, `local_data` is the only supported value, which defines buffer allocated in fast local on-chip memory. It is limited to 100K for all `__local` and
+    `__private` arrays defined inside the kernel as well as all `__local` parameters passed to the kernel. Please, consider that a manual-DMA extension requires double buffering.
+    If the custom layer is detected to run out of local memory, the inference fails.
+    - `dim` – The dim source with the same `direction,port` format used for `WorkSizes` bindings.
+    - `size` – Amount of bytes needed. The current expression syntax supports only expression over dimensions of over selected input/output tensor or constants and may be extended in the future.
+  The example binding below illustrates a kernel with two local buffers passed to the kernel.
+  ```xml
+  <CustomLayer name="GRN" type="MVCL" version="1">
+      <Kernel entry="grn_NCHW">
+          <Source filename="grn.bin"/>
+      </Kernel>
+      <Parameters>
+          <Tensor arg-name="src_data" type="input"         port-index="0"                  format="BFYX"/>
+          <Tensor arg-name="dst_data" type="output"        port-index="0"                  format="BFYX"/>
+          <Data   arg-name="src"      type="local_data"                      dim="input,0" size="X*F*2" />
+          <Data   arg-name="dst"      type="local_data"                      dim="input,0" size="X*F*2" />
+          <Scalar arg-name="C"        type="int"           port-index="0"    source="I.F"               />
+          <Scalar arg-name="bias"     type="float"                           source="bias"              />
+      </Parameters>
+      <WorkSizes dim="input,0" global="X,Y,1" local="X,1,1"/>
+  </CustomLayer>
+```
+
+## Pass Configuration File to Inference Runtime
+
+> **NOTE**: If both native and custom layer implementations are present, the custom kernel has a priority over the native one.
+
+Before loading the network that features the custom layers, provide a separate configuration file and load it using the InferenceEngine::Core::SetConfig() method with the PluginConfigParams::KEY_CONFIG_FILE key and the configuration file name as a value:
+```cpp
+InferenceEngine::Core core;
+// Load custom layers
+core.SetConfig({ { InferenceEngine::PluginConfigParams::KEY_CONFIG_FILE, "<path to the xml file>" } }, "MYRIAD");
+```
+Optionally, set a path to a custom layers description with a pair of `VPU_CUSTOM_LAYERS` and  `/path/to/your/customLayers.xml`
+as a network configuration:
+```cpp
+InferenceEngine::Core core;
+std::map<std::string, std::string> networkConfig;
+config["VPU_CUSTOM_LAYERS"] = "/path/to/your/customLayers.xml";
+// Load custom layers in network config
+auto exeNetwork = core.LoadNetwork(cnnNetwork, "MYRIAD", networkConfig);
+```
+
+## Optimizing Kernels with OpenCL™ for VPU (Intel® Neural Compute Stick 2)
+
+This section provides optimization guidelines on writing custom layers with OpenCL for VPU devices. Knowledge about general OpenCL
+programming model and OpenCL kernel language is assumed and not a subject of this section. The OpenCL model mapping to VPU is described in the table below.
+
+| OpenCL Model  | VPU Mapping|
+|-----|----|
+| Device code | Executed on SHAVE cores    |
+| Private memory | Mapped to CMX internal memory, limited to 100KB per work group, valid only while the work group is executed |
+| Local memory   | Mapped to CMX internal memory, limited to 100KB per work group, valid only while the work group is executed |
+| Global memory  | Mapped to DDR, used to pass execution preserved parameters for inputs, outputs, and blobs                |
+| Work group     | Executed on a single SHAVE core iterating over multiple work items      |
+
+Note that by the OpenCL specification, the work group execution order is not specified. This means that it is your
+responsibility to ensure that race conditions among work groups are not introduced. Custom layer runtime spits evenly
+work grid among available compute resources and executes them in an arbitrary order. This static scheduling approach works best if the load is evenly spread out across work groups, which is a typical case for Deep Learning kernels. The following guidelines are recommended to use for work group partitioning:
+
+1. Split work evenly across work groups.
+2. Adjust work group granularity to maintain equal workload for all compute codes.
+3. Set the maximum number of cores (using the `max-shaves` attribute for the `CustomLayer` node). This keeps more resources for the rest of topology. It is also useful if the kernel scalability reached its limits, which may happen while optimizing memory bound kernels or kernels with poor parallelization.
+4. Try an alternate data layout (`BFXY`/`BYXF`) for the kernel if it improves work group partitioning or data access patterns.
+Consider full topology performance (not just specific layer boost) since data conversion layers would be automatically inserted
+as appropriate.
+
+Offline OpenCL compiler (`clc`) features automatic vectorization over `get_global_id(0)` usage, if uniform access is detected.
+For example, the kernel below could be automatically vectorized:
+```cpp
+__kernel void cvtf32f16(__global float* restrict inImage, __global half*  restrict outImage,
+                        float   scale, float   bais)
+{
+    int idx = get_global_id(0) + get_global_id(1) * get_global_size(0) + get_global_id(2) * get_global_size(0) * get_global_size(1);
+    outImage[idx] = convert_half(inImage[idx]*scale+bais);
+}
+```
+However, this work-group based vectorizer (WGV) conflicts with the default LLVM vectorizer based on superword level parallelism
+(SLP) for the current compiler version. Manual vectorization is recommended to provide the best performance for non-uniform code
+patterns. WGV works if and only if vector types are not used in the code.
+
+Here is a short list of optimization tips:
+
+1. Help auto-vectorizer ensure non-aliasing pointers for kernel parameters by putting `restrict` where possible.
+  - This may give a performance boost, especially for kernels with unrolling, like `ocl_grn` from the example below.
+  - Place `restrict` markers for kernels with manually vectorized codes. In the `ocl_grn` kernel below, the unrolled version without `restrict` is up to 20% slower than the most optimal one, which combines unrolling and `restrict`.
+2. Put `#&zwj;pragma unroll N` to your loop header. Since the compiler does not trigger unrolling by default, it is your responsibility to
+annotate the code with pragmas as appropriate. The `ocl_grn` version with `#&zwj;pragma unroll 4` is up to 50% faster, most of which comes from unrolling the first loop, because LLVM, in general, is better in scheduling 3-stage loops (load-compute-store), while the fist loop
+ `variance += (float)(src_data[c*H*W + y*W + x] * src_data[c*H*W + y*W + x]);` is only 2-stage (load-compute). Please, pay
+attention to unrolling such cases first. Unrolling factor is loop-dependent. Choose the smallest number that
+still improves performance as an optimum between the kernel size and execution speed. For this specific kernel, changing the unroll factor from `4`to `6` results in the same performance, so unrolling factor equal to 4 is an optimum. For Intel® Neural Compute Stick 2, unrolling is conjugated with the automatic software pipelining for load, store, and compute stages:
+```cpp
+__kernel void ocl_grn(__global const half* restrict src_data, __global half* restrict dst_data, int C, float bias)
+{
+    int x = get_global_id(0);
+    int W = get_global_size(0);
+    int y = get_global_id(1);
+    int H = get_global_size(1);
+
+    float variance = bias + 1e-9f;
+
+    #pragma unroll 4
+    for (int c = 0; c < C; c++)
+        variance += (float)(src_data[c*H*W + y*W + x] * src_data[c*H*W + y*W + x]);
+
+    variance = 1.f / native_sqrt(variance);
+
+    #pragma unroll 4
+    for (int c = 0; c < C; c++)
+        dst_data[c*H*W + y*W + x] = (half)((float)src_data[c*H*W + y*W + x] * variance);
+}
+```
+To check the efficiency of WGV, you can compare performance of the kernel above with the kernel below, which is manually vectorized over width:
+```cpp
+__kernel void ocl_grn_line(__global const half* restrict src_data,  __global half* restrict dst_data, int C, int W, float bias)
+{
+    int y   = get_global_id(1);
+    int H   = get_global_size(1);
+
+    for (int x = 0; x < W/8; x++)
+    {
+        float8 variance = (float8)(bias+1e-9f);
+
+        #pragma unroll 4
+        for (int c = 0; c < C; c++)
+        {
+            __global const half8* restrict src_line = ((__global const half8 * restrict)(src_data + c*H*W + y*W));
+            half8 sh = src_line[x];
+            variance += convert_float8(sh*sh);
+        }
+
+        variance = 1.f/native_sqrt(variance);
+
+        #pragma unroll 4
+        for (int c = 0; c < C; c++)
+        {
+            __global const half8* restrict src_line = ((__global const half8 * restrict)(src_data + c*H*W + y*W));
+            __global       half8* restrict dst_line = ((__global       half8 * restrict)(dst_data + c*H*W + y*W));
+
+            dst_line[x] = convert_half8(convert_float8(src_line[x])*variance);
+        }
+    }
+    for (int x = W/8*8; x < W; x++)
+    {
+        float variance = bias+1e-9f;
+        #pragma unroll 4
+        for (int c = 0; c < C; c++)
+            variance += (float)(src_data[c*H*W + y*W + x]*src_data[c*H*W + y*W + x]);
+
+        variance = 1.f/native_sqrt(variance);
+
+        #pragma unroll 4
+        for (int c = 0; c < C; c++)
+            dst_data[c*H*W + y*W + x] = (float)src_data[c*H*W + y*W + x]*variance;
+    }
+}
+```
+Both versions perform the same, but the second one has more complex code.
+
+3. If it is easy to predict the work group size, you can also use the `reqd_work_group_size` kernel attribute to ask the compiler
+to unroll the code up to local size of the work group. Please note that if the kernel is actually executed with the
+different work group configuration, the result is undefined.
+
+4. Prefer to use the `half` compute, if it keeps reasonable accuracy. 16-bit float is a native type for Intel® Neural Compute Stick 2, most of the functions `half_*` are mapped to a single hardware instruction.
+Use the standard `native_*` function for the rest of types.
+
+5. Prefer to use the `convert_half` function over `vstore_half` if conversion to 32-bit float is required. `convert_half` is mapped to a single hardware instruction. For the `cvtf32f16` kernel above, the line `outImage[idx] = convert_half(inImage[idx]*scale+bais);` is 8 times slower than the code with `vstore_half`.
+
+6. Mind early exits. Early exit may be extremely costly for the current version of the `clc` compiler due to conflicts with the
+auto-vectorizer. The generic advice would be to setup local size by `x` dimension equal to inputs or/and outputs width.
+If it is impossible to define the work grid that exactly matches inputs or/and outputs to eliminate checks, for example,
+`if (get_global_id(0) >= width) return`, use line-wise kernel variant with manual vectorization. 
+The kernel example below demonstrates the impact of early exits on kernel performance.
+   ```cpp
+   // Initial version
+   __kernel void reorg(const __global half* restrict src, __global half* restrict out, int stride)
+   {
+     int w = get_global_id(0);
+     int W = get_global_size(0);
+
+     int h = get_global_id(1);
+     int H = get_global_size(1);
+
+     int c = get_global_id(2);
+     int C = get_global_size(2);
+
+     int C2 = C/(stride*stride);
+     int offset = c / C2;
+     int c2 = c - C2 * offset;
+
+     int H2 = H*stride;
+     int W2 = W*stride;
+
+     int h2 = h*stride + offset / stride;
+     int w2 = w*stride + offset - stride * (offset / stride);
+
+     out[W*H*c + W*h + w] = src[W2*H2*c2 + W2*h2 + w2];
+   }
+   ```
+This `reorg` kernel is auto-vectorizable, but an input for YOLO v2 topology is `NCHW=<1,64,26,26>` and it is not multiple of vector width (which is `8` for `half` data type). As a result, the Inference Engine does not select the auto-vectorized kernel.
+To compare performance of auto-vectorized and scalar version of the kernel, change the input size to`NCHW=<1,64,26,32>`. This allows the auto-vectorized version to be selected by the Inference Engine and can give you about 30% uplift.
+Since the auto-vectorized version is faster, it makes sense to enable it for the YOLO v2 topology input size by setting the local size multiple of vector (e.g. 32) and adjust global sizes accordingly. As a result, the execution work grid exceeds actual input dimension, so out-of-bound checks should be inserted. See the updated kernel version below:
+   ```cpp
+   // Version with out-of-bound checks added
+   __kernel void reorg(const __global half* restrict src, __global half* restrict out, int W, int stride)
+   {
+     int w = get_global_id(0);
+     w = min(w, W-1);
+
+     int h = get_global_id(1);
+     int H = get_global_size(1);
+
+     int c = get_global_id(2);
+     int C = get_global_size(2);
+
+     int C2 = C/(stride*stride);
+     int offset = c / C2;
+     int c2 = c - C2 * offset;
+
+     int H2 = H*stride;
+     int W2 = W*stride;
+
+     int h2 = h*stride + offset / stride;
+     int w2 = w*stride + offset - stride * (offset / stride);
+
+     out[W*H*c + W*h + w] = src[W2*H2*c2 + W2*h2 + w2];
+   }
+   ```
+This code performs the same as the initial kernel above (scalar) due to branching overhead. If you replace min/max expression `w = min(w, W-1);` with `if (w >= W) return;`, runtime increases up to 2x against to code without branching (initial version).<br>
+If branching is inevitable for your element-based kernel, it is recommended to change the scheme to line-based. See the kernel variant below:
+```cpp
+// Line-wise version
+__kernel void reorg(const __global half* restrict src, __global half* restrict out, int H, int W, int stride)
+{
+    int h = min((int)get_global_id(0), H-1);
+
+    int c = get_global_id(1);
+    int C = get_global_size(1);
+    int C2 = C/(stride*stride);
+    int offset = c / C2;
+    int c2 = c - C2 * offset;
+
+    int H2 = H*stride;
+    int W2 = W*stride;
+
+    for (int w = 0; w < W; ++w)
+    {
+        int h2 = h*stride + offset / stride;
+        int w2 = w*stride + offset - stride * (offset / stride);
+
+        out[W*H*c + W*h + w] = src[W2*H2*c2 + W2*h2 + w2];
+    }
+}
+```
+This decreases the execution time up to 40% against the best performing vectorized kernel without early exits (initial version).
+7. Reuse computations among work items by using line-based kernels or sharing values though `__local` memory.
+8. Improve data access locality. Most of custom kernels are memory bound while convolution and fully connected layers are hardware-implemented. The code below demonstrates a further optimized version of the `reorg` kernel unrolled by `stride`:
+   ```cpp
+   // Unrolled line-wise version
+   __kernel void reorg_unrolled_by_stride(const __global half* restrict src, __global half* restrict dst,
+                                          int H, int W, int stride)
+   {
+     int h = min((int)get_global_id(0), H-1);
+
+     int c2 = get_global_id(1);
+     int C2 = get_global_size(1);
+     int C = C2*stride*stride;
+
+     int H2 = H*stride;
+     int W2 = W*stride;
+
+     for (int stride_y = 0; stride_y < stride; stride_y++)
+       for (int stride_x = 0; stride_x < stride; stride_x++)
+         for (int w2 = 0, w = 0; w < W; w2 += stride, w++)
+           dst[W*H*C2*(stride_y*stride+stride_x) + W*H*c2 + W*h + w] = src[W2*H2*c2 + W2*h*stride + W2*stride_y + w2 + stride_x];
+   }
+   ```
+`scr` data in this case loaded only once. As the result, the cycle count drops up to 45% against the line-wise version.
+
+9. Copy data from `__dlobal` to `__local` or `__private` memory if the data is accessed more than once. Access to
+`__dlobal` memory is orders of magnitude slower than access to `__local`/`__private` due to statically scheduled pipeline, which
+stalls completely on memory access without any prefetch. The same recommendation is applicable for scalar load/store
+from/to a `__blobal` pointer since work-group copying could be done in a vector fashion.
+
+10. Use a manual DMA extension. Local (on-chip) memory throughput is up to 24x higher than DDR throughput. Starting from OpenVINO™ 2020.1, VPU OpenCL features manual-DMA kernel extension to copy sub-tensor used by work group into local memory and performing compute without DDR evolved. Here is the simple GRN kernel implementation that runs over DDR. Local size is equal to (width of the input tensor, 1, 1) to define a large enough work group to get code automatically vectorized and unrolled, while global size is (width of the input tensor, height of the input tensor, 1):
+   ```cpp
+   __kernel void grn_NCHW(
+     __global const half* restrict src_data,
+     __global       half* restrict dst_data,
+     int C,
+     float bias)
+   {
+     float variance = bias + 1e-9f;
+
+     #pragma unroll 4
+     for (int c = 0; c < C; c++)
+     {
+       float val = (float) src_data[c*get_global_size(1)*get_global_size(0) + get_global_id(1)*get_global_size(0) + get_global_id(0)];
+       variance += val*val;
+     }
+
+     half hvariance = (half)(native_rsqrt((half)(variance/16.f))*0.25f);
+
+     #pragma unroll 4
+     for (int c = 0; c < C; c++)
+     {
+       dst_data[c*get_global_size(1)*get_global_size(0) + get_global_id(1)*get_global_size(0) + get_global_id(0)]
+       = src_data[c*get_global_size(1)*get_global_size(0) + get_global_id(1)*get_global_size(0) + get_global_id(0)] * hvariance;
+     }
+   }
+   ```
+This kernel can be rewritten to introduce special data binding `__dma_preload` and `__dma_postwrite intrinsics`. This means that instead of one kernel, a group of three kernels should be implemented: `kernelName`, `__dma_preload_kernelName` and `__dma_postwrite_kernelName`.  `__dma_preload_kernelName` for a particular work group `n` is guaranteed to be executed before `n`-th work group itself, while `__dma_postwrite_kernelName` is guarantied to be executed after a corresponding work group. You can define one of those functions that are intended to be used to copy data from-to `__global` and `__local` memory. The syntactics requires exact functional signature match. The example below illustrates how to prepare your kernel for manual-DMA.
+   ```cpp
+   __kernel void __dma_preload_grn_NCHW(
+     __global const half* restrict src,
+     __global       half* restrict dst,
+     __local        half* restrict local_src,
+     __local        half* restrict local_dst,
+     int C,
+     float bias)
+   {
+     // ToDO: copy required piece of src tensor into local_src
+   }
+   
+   __kernel void __dma_postwrite_grn_NCHW(
+     __global const half* restrict src,
+     __global       half* restrict dst,
+     __local  const half* restrict local_src,
+     __local        half* restrict local_dst,
+     int C,
+     float bias)
+   {
+     // ToDO: copy back computed piece of local_dst into dst
+   }
+   
+   __kernel void grn_NCHW(
+     __global const half* restrict src_data,
+     __global       half* restrict dst_data,
+     __local        half* restrict src,
+     __local        half* restrict dst,
+     int C,
+     float bias)
+   {
+     // same as the example above
+   }
+   ```
+GRN kernel operates on channel-major tensors to compute average over full channel range and then normalizes input elements to produce the output.
+As a part of manual DMA extension, a group of work group copy functions are introduced in addition to `async_work_group_copy`, which is also mapped to DMA call.
+
+Here is the list of supported functions:
+```cpp
+// 2D sub-tensor copy
+event_t WorkGroupDmaCreateStrideTransaction(
+                const local T *src,

+```
+where `T` can be `uchar`, `char`, `short`, `ushort`, `int`, `uint`, `long`, `ulong`, `half` or `float`.
+
+Modified version of the GRN kernel could be the following:
+```cpp
+__kernel void __dma_preload_grn_NCHW(
+    __global const half* restrict src,
+    __global       half* restrict dst,

+}
+
+__kernel void __dma_postwrite_grn_NCHW(

+}
+```
+
+Please note `get_local_size` and `get_local_id` usage inside the kernel. 21x speedup is expected for a kernel on enet-curbs setup since it was completely limited by memory usage.
+
+An alternative method of using DMA is to use work item copy extension. Those functions are executed inside a kernel and requires work groups equal to single work item.
+
+Here is the list of supported work item functions:
+```cpp

+
+List of deprecated API for kernels development:
+ * `InferenceEngine::IExtension::getPrimitiveTypes(char**& types, unsigned int& size, ResponseDesc* resp)` method
+ * `InferenceEngine::IExtension::getFactoryFor(ILayerImplFactory *&factory, const CNNLayer *cnnLayer, ResponseDesc *resp)` method
+ * `InferenceEngine::ILayerImplFactory` class
+
+>**NOTE**: This guide demonstrates how to use deprecated API for kernels creation. However, keep in mind that this API will be deleted soon.
+
+1. Create your custom layer factory `CustomLayerFactory` class:
+```cpp
+// custom_layer.h
+// A CustomLayerFactory class is an example layer, which makes exponentiation by 2 for the input and does not change dimensions
+class CustomLayerFactory {
+
+};
+```
+2. Inherit it from the abstract `InferenceEngine::ILayerImplFactory` class: 
+```cpp
+// custom_layer.h
+class CustomLayerFactory: public InferenceEngine::ILayerImplFactory {
+
+};
+```
+
+3. Create a constructor, a virtual destructor, and a data member to keep the layer info:
+```cpp
+// custom_layer.h
+class CustomLayerFactory: public InferenceEngine::ILayerImplFactory {
+public:
+    explicit CustomLayerFactory(const CNNLayer *layer): cnnLayer(*layer) {}
+private:
+  CNNLayer cnnLayer;
+};
+```
+
+4. Overload and implement the abstract methods `getShapes` and `getImplementations` of the `InferenceEngine::ILayerImplFactory` class:
+```cpp
+// custom_layer.h
+class CustomLayerFactory: public InferenceEngine::ILayerImplFactory {
+public:
+    // ... constructor and destructor
+
+    StatusCode getShapes(const std::vector<TensorDesc>& inShapes, std::vector<TensorDesc>& outShapes, ResponseDesc *resp) noexcept override {
+        if (cnnLayer == nullptr) {
+            std::string errorMsg = "Cannot get cnn layer!";
+            errorMsg.copy(resp->msg, sizeof(resp->msg) - 1);
+            return GENERAL_ERROR;
+        }
+        if (inShapes.size() != 1) {
+            std::string errorMsg = "Incorrect input shapes!";
+            errorMsg.copy(resp->msg, sizeof(resp->msg) - 1);
+            return GENERAL_ERROR;
+        }
+        outShapes.clear();
+        outShapes.emplace_back(inShapes[0]);
+        return OK;
+    }
+
+    StatusCode getImplementations(std::vector<ILayerImpl::Ptr>& impls, ResponseDesc *resp) noexcept override {
+        // You can add cnnLayer to implementation if it is necessary
+        impls.push_back(ILayerImpl::Ptr(new CustomLayerImpl()));
+        return OK;
+    }
+};
+```
+5. Create your custom layer implementation `CustomLayerImpl` class using the [instruction](../CPU_Kernel.md).
+
+6. Implement methods in the `Extension` class:
+```cpp
+// custom_extension.h
+class CustomExtention : public InferenceEngine::IExtension {
+public:
+    // ... utility methods
+    // Retruns the list of supported kernels/layers
+    StatusCode getPrimitiveTypes(char**& types, unsigned int& size, ResponseDesc* resp) noexcept override {
+        std::string type_name = "CustomLayer";
+        types = new char *[1];
+        size = 1;
+        types[0] = new char[type_name.size() + 1];
+        std::copy(type_name.begin(), type_name.end(), types[0]);
+        types[0][type_name.size()] = '\0';
+        return OK;
+    }
+    // Main function
+    StatusCode getFactoryFor(ILayerImplFactory *&factory, const CNNLayer *cnnLayer, ResponseDesc *resp) noexcept override {
+        if (cnnLayer->type != "CustomLayer") {
+            std::string errorMsg = std::string("Factory for ") + cnnLayer->type + " wasn't found!";
+            errorMsg.copy(resp->msg, sizeof(resp->msg) - 1);
+            return NOT_FOUND;
+        }

+# Old ShapeInference Extensibility API {#openvino_docs_IE_DG_Extensibility_DG_deprecated_ShapeInfer}
+
+The new approach to shape inference suggests a creation of a custom nGraph operation that contains a special method for shape inference. 
+The following classes and methods were deprecated:
+
+ * `InferenceEngine::IShapeInferExtension` class
+ * `InferenceEngine::IShapeInferExtension::getShapeInferTypes(char**&, unsigned int&, ResponseDesc*)` method
+ * `InferenceEngine::IShapeInferExtension::getShapeInferImpl(IShapeInferImpl::Ptr&, const char*, ResponseDesc*)` method
+
+However, the old approach with the `InferenceEngine::IShapeInferExtension` method still works for already existing custom layers.
+Custom Shape Inference functions are registered by calling `InferenceEngine::ICNNNetwork::AddExtension` with the implemented `InferenceEngine::IShapeInferExtension` method, which is a holder of custom implementations. 
+The holder requires to implement two key methods:
+* `InferenceEngine::IShapeInferExtension::getShapeInferImpl` - Returns custom shape inference implementation for the given type. 
+* `InferenceEngine::IShapeInferExtension::getShapeInferTypes` - Provides all custom types.
+
+Custom shape inference implementation is represented by the `InferenceEngine::IShapeInferImpl::inferShapes` method.
+
+It is impossible to overwrite built-in shape inference functions. Custom type must be different from the supported ones.

+Using GPU Kernels Tuning {#openvino_docs_IE_DG_GPU_Kernels_Tuning}
+======================
+
+GPU Kernels Tuning allows you to tune models, so the heavy computational layers are configured to fit better into
+hardware, which the tuning was done on. It is required to achieve best performance on GPU.
+> **NOTE** Currently only convolution and fully connected layers undergo tuning process. It means that the performance boost depends on the amount of that layers in the model.
+
+OpenVINO™ releases include the `<INSTALL_DIR>/inference_engine/bin/intel64/Release/cache.json` file with pretuned data for current state of the art models. It is highly recommended to do the
+tuning for new kind of models, hardwares or drivers.
+
+## Tuned data
+
+GPU tuning data is saved in JSON format.
+File's content is composed of 2 types of attributes and 1 type of value:
+1. Execution units number - this attribute splits the content into different EU sections.
+2. Hash - hashed tuned kernel data.
+Key: Array with kernel name and kernel's mode index.
+
+## Usage
+
+---
+
+You can activate Kernels Tuning process by setting `KEY_TUNING_MODE` flag to `TUNING_CREATE` and `KEY_TUNING_FILE` to `<"filename">` in a configuration map that is
+passed to the plugin while loading a network.
+This configuration modifies the behavior of the `ExecutableNetwork` object. Instead of standard network compilation, it will run the tuning process.
+Please keep in mind that the tuning can be very time consuming. The bigger the network, the longer it will take.
+File with tuned data is the result of this step.
+
+> **NOTE** If a filename passed to `KEY_TUNING_FILE` points to existing tuned data and you are tuning a new model, then this file will be extended by new data. This allows you to extend existing `cache.json` provided in the OpenVINO™ release package. 
+
+The example below shows how to set and use the key files:
+```cpp
+Core ie;          
+  ie.SetConfig({{ CONFIG_KEY(TUNING_MODE), CONFIG_VALUE(TUNING_CREATE) }}, "GPU");
+  ie.SetConfig({{ CONFIG_KEY(TUNING_FILE), "/path/to/tuning/file.json" }}, "GPU");
+  // Further LoadNetwork calls will use the specified tuning parameters
+```
+---
+
+You can activate the inference with tuned data by setting `KEY_TUNING_MODE` flag to `TUNING_USE_EXISTING` and
+`KEY_TUNING_FILE` flag to `<"filename">`. 
+
+GPU backend will process the content of the file during network compilation to configure the OpenCL kernels for the best performance.

+# Graph Debug Capabilities {#openvino_docs_IE_DG_Graph_debug_capabilities}
+
+Inference Engine supports two different objects for a graph representation: the nGraph function and 
+CNNNetwork. Both representations provide an API to get detailed information about the graph structure.
+
+## nGraph Function
+
+To receive additional messages about applied graph modifications, rebuild the nGraph library with 
+the `-DNGRAPH_DEBUG_ENABLE=ON` option.
+
+To enable serialization and deserialization of the nGraph function to a JSON file, rebuild the 
+nGraph library with the `-DNGRAPH_JSON_ENABLE=ON` option. To serialize or deserialize the nGraph
+function, call the nGraph function as follows:
+
+```cpp
+#include <ngraph/serializer.hpp>
+
+std::shared_ptr<ngraph::Function> nGraph;
+...
+ngraph::serialize("test_json.json", nGraph);        // For graph serialization
+std::ifstream file("test_json.json");               // Open a JSON file
+nGraph = ngraph::deserialize(file);                 // For graph deserialization
+```
+
+To visualize the nGraph function to the xDot format or to an image file, use the 
+`ngraph::pass::VisualizeTree` graph transformation pass:
+```cpp
+#include <ngraph/pass/visualize_tree.hpp>
+
+std::shared_ptr<ngraph::Function> nGraph;
+...
+std::vector<std::shared_ptr<ngraph::Function>> g2{nGraph};
+ngraph::pass::VisualizeTree("after.png").run_on_module(g2);     // Visualize the nGraph function to an image
+```
+
+## CNNNetwork
+
+To serialize the CNNNetwork to the Inference Engine Intermediate Representation (IR) format, use the 
+`CNNNetwork::serialize(...)` method:
+```cpp
+std::shared_ptr<ngraph::Function> nGraph;
+...
+CNNNetwork network(nGraph);
+network.serialize("test_ir.xml", "test_ir.bin");
+```
+> **NOTE**: CNNNetwork created from the nGraph function might differ from the original nGraph 
+> function because the Inference Engine applies some graph transformation.

+Introduction to Inference Engine Device Query API {#openvino_docs_IE_DG_InferenceEngine_QueryAPI}
+===============================
+
+This section provides a high-level description of the process of querying of different device properties and configuration values.
+Refer to the [Hello Query Device Sample](../../inference-engine/samples/hello_query_device/README.md) sources and [Multi-Device Plugin guide](supported_plugins/MULTI.md) for example of using the Inference Engine Query API in user applications.
+
+## Using the Inference Engine Query API in Your Code
+
+The Inference Engine `Core` class provides the following API to query device information, set or get different device configuration properties:
+
+* <code>InferenceEngine::Core::GetAvailableDevices</code> - Provides a list of available devices. If there are more than one instance of a specific device, the devices are enumerated with `.suffix` where `suffix` is a unique string identifier. The device name can be passed to all methods of the `InferenceEngine::Core` class that work with devices, for example `InferenceEngine::Core::LoadNetwork`.
+* <code>InferenceEngine::Core::GetMetric</code> - Provides information about specific device.
+  <code>InferenceEngine::Core::GetConfig</code> - Gets the current value of a specific configuration key.
+* <code>InferenceEngine::Core::SetConfig</code> - Sets a new value for the configuration key.
+
+The `InferenceEngine::ExecutableNetwork` class is also extended to support the Query API:
+
+* <code>InferenceEngine::ExecutableNetwork::GetMetric</code>
+* <code>InferenceEngine::ExecutableNetwork::GetConfig</code>
+* <code>InferenceEngine::ExecutableNetwork::SetConfig</code>
+
+## Query API in the Core Class
+
+### GetAvailableDevices
+
+```cpp
+InferenceEngine::Core core;
+std::vector<std::string> availableDevices = ie.GetAvailableDevices();
+```
+
+The function returns list of available devices, for example:
+```
+MYRIAD.1.2-ma2480
+MYRIAD.1.4-ma2480
+FPGA.0
+FPGA.1
+CPU
+GPU
+...
+```
+
+Each device name can then be passed to:
+
+* `InferenceEngine::Core::LoadNetwork` to load the network to a specific device.
+* `InferenceEngine::Core::GetMetric` to get common or device specific metrics.
+* All other methods of the `Core` class that accept `deviceName`.
+
+### GetConfig()
+
+The code below demonstrates how to understand whether `HETERO` device dumps `.dot` files with split graphs during the split stage:
+
+```cpp
+InferenceEngine::Core core;
+bool dumpDotFile = core.GetConfig("HETERO", HETERO_CONFIG_KEY(DUMP_GRAPH_DOT)).as<bool>();
+```
+
+For documentation about common configuration keys, refer to `ie_plugin_config.hpp`. Device specific configuration keys can be found in corresponding plugin folders.
+
+### GetMetric()
+
+* To extract device properties such as available device, device name, supported configuration keys, and others, use the `InferenceEngine::Core::GetMetric` method:
+
+```cpp
+InferenceEngine::Core core;
+std::string cpuDeviceName = core.GetMetric("GPU", METRIC_KEY(FULL_DEVICE_NAME)).as<std::string>();
+```
+
+A returned value looks as follows: `Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz`.
+
+> **NOTE**: All metrics have specific type, which is specified during metric instantiation. The list of common device-agnostic metrics can be found in `ie_plugin_config.hpp`. Device specific metrics (for example, for `HDDL`, `MYRIAD` devices) can be found in corresponding plugin folders.
+
+## Query API in the ExecutableNetwork Class
+
+### GetMetric()
+
+The method is used to get executable network specific metric such as `METRIC_KEY(OPTIMAL_NUMBER_OF_INFER_REQUESTS)`:
+```cpp
+InferenceEngine::Core core;
+auto exeNetwork = core.LoadNetwork(network, "CPU");
+auto nireq = exeNetwork.GetMetric(METRIC_KEY(OPTIMAL_NUMBER_OF_INFER_REQUESTS)).as<unsigned int>();
+```
+
+Or the current temperature of `MYRIAD` device:
+```cpp
+InferenceEngine::Core core;
+auto exeNetwork = core.LoadNetwork(network, "MYRIAD");
+float temperature = exeNetwork.GetMetric(METRIC_KEY(DEVICE_THERMAL)).as<float>();
+```
+
+### GetConfig()
+
+The method is used to get information about configuration values the executable network has been created with:
+
+```cpp
+InferenceEngine::Core core;
+auto exeNetwork = core.LoadNetwork(network, "CPU");
+auto ncores = exeNetwork.GetConfig(PluginConfigParams::KEY_CPU_THREADS_NUM).as<std::string>();
+```
+
+### SetConfig()
+
+The only device that supports this method is [Multi-Device](supported_plugins/MULTI.md).

+## Introduction
+
+A lot of investigation was made in the field of deep learning with the idea of using low precision computations during inference in order to boost deep learning pipelines and gather higher performance. For example, one of the popular approaches is to shrink the precision of activations and weights values from `fp32` precision to smaller ones, for example, to `fp11` or `int8`. For more information about this approach, refer to 
+**Brief History of Lower Precision in Deep Learning** section in [this whitepaper](https://software.intel.com/en-us/articles/lower-numerical-precision-deep-learning-inference-and-training).
+
+8-bit computations (referred to as `int8`) offer better performance compared to the results of inference in higher precision (for example, `fp32`), because they allow loading more data into a single processor instruction. Usually the cost for significant boost is a reduced accuracy. However, it is proved that an accuracy drop can be negligible and depends on task requirements, so that the application engineer can set up the maximum accuracy drop that is acceptable.
+
+Current Inference Engine solution for low-precision inference uses Intel MKL-DNN and supports inference of the following layers in 8-bit integer computation mode:
+* Convolution
+* FullyConnected
+* ReLU
+* ReLU6
+* Reshape
+* Permute
+* Pooling
+* Squeeze
+* Eltwise
+* Concat
+* Resample
+* MVN
+
+This means that 8-bit inference can only be performed with the CPU plugin on the layers listed above. All other layers are executed in the format supported by the CPU plugin: 32-bit floating point format (`fp32`).
+
+## Low-Precision 8-bit Integer Inference Workflow
+
+For 8-bit integer computations, a model must be quantized. If the model is not quantized then you can use the [Post-Training Optimization Tool](@ref pot_README) to quantize the model. The quantization process adds `FakeQuantize` layers on activations and weights for most layers. Read more about mathematical computations under the hood in the [white paper](https://intel.github.io/mkl-dnn/ex_int8_simplenet.html).
+
+8-bit inference pipeline includes two stages (also refer to the figure below):
+1. *Offline stage*, or *model quantization*. During this stage, `FakeQuantize` layers are added before most layers to have quantized tensors before layers in a way that low-precision accuracy drop for 8-bit integer inference satisfies the specified threshold. The output of this stage is a quantized model. Quantized model precision is not changed, quantized tensors are in original precision range (`fp32`). `FakeQuantize` layer has `Quantization Levels` attribute whic defines quants count. Quants count defines precision which is used during inference. For `int8` range `Quantization Levels` attribute value has to be 255 or 256.
+
+2. *Run-time stage*. This stage is an internal procedure of the [CPU Plugin](supported_plugins/CPU.md). During this stage, the quantized model is loaded to the plugin. The plugin updates each `FakeQuantize` layer on activations and weights to have `FakeQuantize` output tensor values in low precision range. 
+![int8_flow]
+
+### Offline Stage: Model Quantization
+
+To infer a layer in low precision and get maximum performance, the input tensor for the layer has to be quantized and each value has to be in the target low precision range. For this purpose, `FakeQuantize` layer is used in the OpenVINO™ intermediate representation file (IR). To quantize the model, you can use the [Post-Training Optimization Tool](@ref pot_README) delivered with the Intel® Distribution of OpenVINO™ toolkit release package.
+
+When you pass the calibrated IR to the [CPU plugin](supported_plugins/CPU.md), the plugin automatically recognizes it as a quantized model and performs 8-bit inference. Note, if you pass a quantized model to another plugin that does not support 8-bit inference, the model is inferred in precision that this plugin supports.
+
+### Run-Time Stage: Quantization
+
+This is the second stage of the 8-bit integer inference. After you load the quantized model IR to a plugin, the pluing uses the `Low Precision Transformation` component to update the model to infer it in low precision:
+* Updates `FakeQuantize` layers to have quantized output tensors in low precision range and add dequantization layers to compensate the update. Dequantization layers are pushed through as many layers as possible to have more layers in low precision. After that, most layers have quantized input tensors in low precision range and can be inferred in low precision. Ideally, dequantization layers should be fused in next `FakeQuantize` or `ScaleShift` layers.
+* Weights are quantized and stored in `Const` layers.
+* Biases are updated to avoid shifts in dequantization layers.
+
+## Performance Counters
+
+Information about layer precision is stored in the performance counters that are
+available from the Inference Engine API. The layers have the following marks:
+* Suffix `I8` for layers that had 8-bit data type input and were computed in 8-bit precision
+* Suffix `FP32` for layers computed in 32-bit precision
+
+For example, the performance counters table for the Inception model can look as follows:
+
+```

+Integrate the Inference Engine with Your Application {#openvino_docs_IE_DG_Integrate_with_customer_application_new_API}
+===============================
+
+This section provides a high-level description of the process of integrating the Inference Engine into your application.
+Refer to the [Hello Classification Sample](../../inference-engine/samples/hello_classification/README.md) sources
+for example of using the Inference Engine in applications.
+
+> **NOTE**: For 2019 R2 Release, the new Inference Engine Core API is introduced. This guide is updated to reflect the new API approach.
+> The Inference Engine Plugin API is still supported, but is going to be deprecated in future releases. Please, refer to [Migration from Inference Engine Plugin API to Core API](Migration_CoreAPI.md) guide to update your application.
+
+## Use the Inference Engine API in Your Code
+
+The core `libinference_engine.so` library implements loading and parsing a model Intermediate Representation (IR), and triggers inference using a specified device. The core library has the following API:
+
+* `InferenceEngine::Core`
+* `InferenceEngine::Blob`, `InferenceEngine::TBlob`,
+  `InferenceEngine::NV12Blob`
+* `InferenceEngine::BlobMap`
+* `InferenceEngine::InputsDataMap`, `InferenceEngine::InputInfo`,
+* `InferenceEngine::OutputsDataMap`
+
+C++ Inference Engine API wraps the capabilities of core library:
+
+* `InferenceEngine::CNNNetwork`
+* `InferenceEngine::ExecutableNetwork`
+* `InferenceEngine::InferRequest`
+
+## Integration Steps
+
+Integration process includes the following steps:
+![integration_process]
+
+1) **Create Inference Engine Core** to manage available devices and read network objects:
+```cpp
+InferenceEngine::Core core;
+```
+
+2) **Read a model IR** created by the Model Optimizer (.xml is supported format):
+```cpp
+auto network = core.ReadNetwork("Model.xml");
+```
+**Or read the model from ONNX format** (.onnx and .prototxt are supported formats)
+```cpp
+auto network = core.ReadNetwork("model.onnx");
+```
+
+3) **Configure input and output**. Request input and output information using `InferenceEngine::CNNNetwork::getInputsInfo()`, and `InferenceEngine::CNNNetwork::getOutputsInfo()`
+methods:
+```cpp
+/** Take information about all topology inputs **/
+InferenceEngine::InputsDataMap input_info = network.getInputsInfo();
+/** Take information about all topology outputs **/
+InferenceEngine::OutputsDataMap output_info = network.getOutputsInfo();
+```
+  Optionally, set the number format (precision) and memory layout for inputs and outputs. Refer to the
+  [Supported configurations](supported_plugins/Supported_Devices.md) chapter to choose the relevant configuration.
+
+  You can also allow input of any size. To do this, mark each input as resizable by setting a desired resize algorithm (e.g. `BILINEAR`) inside of the appropriate input info.
+
+  Basic color format conversions are supported as well. By default, the Inference Engine assumes
+  that the input color format is `BGR` and color format conversions are disabled. The Inference
+  Engine supports the following color format conversions:
+  * `RGB->BGR`
+  * `RGBX->BGR`
+  * `BGRX->BGR`
+  * `NV12->BGR`
+
+  where `X` is a channel that will be ignored during inference. To enable the conversions, set a
+  desired color format (for example, `RGB`) for each input inside of the appropriate input info.
+
+  If you want to run inference for multiple images at once, you can use the built-in batch
+  pre-processing functionality.
+
+> **NOTE**: Batch pre-processing is not supported if input color format is set to `ColorFormat::NV12`.
+
+  You can use the following code snippet to configure input and output:
+```cpp
+/** Iterate over all input info**/
+for (auto &item : input_info) {
+    auto input_data = item.second;
+    input_data->setPrecision(Precision::U8);
+    input_data->setLayout(Layout::NCHW);
+    input_data->getPreProcess().setResizeAlgorithm(RESIZE_BILINEAR);
+    input_data->getPreProcess().setColorFormat(ColorFormat::RGB);
+}
+/** Iterate over all output info**/
+for (auto &item : output_info) {
+    auto output_data = item.second;
+    output_data->setPrecision(Precision::FP32);
+    output_data->setLayout(Layout::NC);
+}
+```
+
+> **NOTE**: NV12 input color format pre-processing differs from other color conversions. In case of NV12,
+>  Inference Engine expects two separate image planes (Y and UV). You must use a specific
+>  `InferenceEngine::NV12Blob` object instead of default blob object and set this blob to
+>  the Inference Engine Infer Request using `InferenceEngine::InferRequest::SetBlob()`.
+>  Refer to [Hello NV12 Input Classification C++ Sample](../../inference-engine/samples/hello_nv12_input_classification/README.md)
+>  for more details.
+
+  If you skip this step, the default values are set:
+
+  * no resize algorithm is set for inputs
+  * input color format - `ColorFormat::RAW` meaning that input does not need color
+    conversions
+  * input and output precision - `Precision::FP32`
+  * input layout - `Layout::NCHW`
+  * output layout depends on number of its dimensions:
+
+|Number of dimensions |  5    |  4   |   3 |  2 |  1 |
+|:--------------------|-------|------|-----|----|----|
+|Layout               | NCDHW | NCHW | CHW | NC | C  |
+
+4) **Load the model** to the device using `InferenceEngine::Core::LoadNetwork()`:
+```cpp
+auto executable_network = core.LoadNetwork(network, "CPU");
+```
+    It creates an executable network from a network object. The executable network is associated with single hardware device.
+    It is possible to create as many networks as needed and to use them simultaneously (up to the limitation of the hardware resources).
+    Third parameter is a configuration for plugin. It is map of pairs: (parameter name, parameter value). Choose device from
+     [Supported devices](supported_plugins/Supported_Devices.md) page for more details about supported configuration parameters.
+```cpp
+/** Optional config. E.g. this enables profiling of performance counters. **/
+std::map<std::string, std::string> config = {{ PluginConfigParams::KEY_PERF_COUNT, PluginConfigParams::YES }};
+auto executable_network = core.LoadNetwork(network, "CPU", config);
+```
+
+5) **Create an infer request**:
+```cpp
+auto infer_request = executable_network.CreateInferRequest();
+```
+
+6) **Prepare input**. You can use one of the following options to prepare input:
+    * **Optimal way for a single network.** Get blobs allocated by an infer request using `InferenceEngine::InferRequest::GetBlob()`
+    and feed an image and the input data to the blobs. In this case, input data must be aligned (resized manually) with a
+    given blob size and have a correct color format.
+```cpp
+/** Iterate over all input blobs **/
+for (auto & item : inputInfo) {
+    auto input_name = item->first;
+    /** Get input blob **/
+    auto input = infer_request.GetBlob(input_name);
+    /** Fill input tensor with planes. First b channel, then g and r channels **/
+    ...
+}
+```
+    * **Optimal way for a cascade of networks (output of one network is input for another).** Get output blob from the first
+    request using `InferenceEngine::InferRequest::GetBlob()` and set it as input for the second request using
+    `InferenceEngine::InferRequest::SetBlob()`.
+```cpp
+auto output = infer_request1->GetBlob(output_name);
+infer_request2->SetBlob(input_name, output);
+```
+    * **Optimal way to handle ROI (a ROI object located inside of input of one network is input for another).** It is
+    possible to re-use shared input by several networks. You do not need to allocate separate input blob for a network if
+    it processes a ROI object located inside of already allocated input of a previous network. For instance, when first
+    network detects objects on a video frame (stored as input blob) and second network accepts detected bounding boxes
+    (ROI inside of the frame) as input.
+    In this case, it is allowed to re-use pre-allocated input blob (used by first network) by second network and just crop
+    ROI without allocation of new memory using `InferenceEngine::make_shared_blob()` with passing of
+    `InferenceEngine::Blob::Ptr` and `InferenceEngine::ROI` as parameters.
+```cpp
+/** inputBlob points to input of a previous network and
+    cropROI contains coordinates of output bounding box **/
+InferenceEngine::Blob::Ptr inputBlob;
+InferenceEngine::ROI cropRoi;
+...
+
+/** roiBlob uses shared memory of inputBlob and describes cropROI
+    according to its coordinates **/
+auto roiBlob = InferenceEngine::make_shared_blob(inputBlob, cropRoi);
+infer_request2->SetBlob(input_name, roiBlob);
+```
+      Make sure that shared input is kept valid during execution of each network. Otherwise, ROI blob may be corrupted if the
+      original input blob (that ROI is cropped from) has already been rewritten.
+
+    * Allocate input blobs of the appropriate types and sizes, feed an image and the input data to the blobs, and call
+    `InferenceEngine::InferRequest::SetBlob()` to set these blobs for an infer request:
+```cpp
+/** Iterate over all input blobs **/
+for (auto & item : inputInfo) {
+    auto input_data = item->second;
+    /** Create input blob **/
+    InferenceEngine::TBlob<unsigned char>::Ptr input;
+    // assuming input precision was asked to be U8 in prev step
+    input = InferenceEngine::make_shared_blob<unsigned char, InferenceEngine::SizeVector>(InferenceEngine::Precision:U8, input_data->getDims());
+    input->allocate();
+    infer_request->SetBlob(item.first, input);
+
+    /** Fill input tensor with planes. First b channel, then g and r channels **/
+    ...
+}
+```
+      A blob can be filled before and after `SetBlob()`.
+
+> **NOTE:**
+>
+> * `SetBlob()` method compares precision and layout of an input blob with ones defined on step 3 and
+> throws an exception if they do not match. It also compares a size of the input blob with input
+> size of the read network. But if input was configured as resizable, you can set an input blob of
+> any size (for example, any ROI blob). Input resize will be invoked automatically using resize
+> algorithm configured on step 3. Similarly to the resize, color format conversions allow the color
+> format of an input blob to differ from the color format of the read network. Color format
+> conversion will be invoked automatically using color format configured on step 3.
+>
+> * `GetBlob()` logic is the same for pre-processable and not pre-processable input. Even if it is
+> called with input configured as resizable or as having specific color format, a blob allocated by
+> an infer request is returned. Its size and color format are already consistent with the
+> corresponding values of the read network. No pre-processing will happen for this blob. If you
+> call `GetBlob()` after `SetBlob()`, you will get the blob you set in `SetBlob()`.
+
+7) **Do inference** by calling the `InferenceEngine::InferRequest::StartAsync` and `InferenceEngine::InferRequest::Wait`
+methods for asynchronous request:
+```cpp
+infer_request->StartAsync();
+infer_request.Wait(IInferRequest::WaitMode::RESULT_READY);
+```
+
+or by calling the `InferenceEngine::InferRequest::Infer` method for synchronous request:
+```cpp
+sync_infer_request->Infer();
+```
+`StartAsync` returns immediately and starts inference without blocking main thread, `Infer` blocks
+ main thread and returns when inference is completed.
+Call `Wait` for waiting result to become available for asynchronous request.
+
+There are three ways to use it:
+* specify maximum duration in milliseconds to block for. The method is blocked until the specified timeout has elapsed,
+or the result becomes available, whichever comes first.
+* `InferenceEngine::IInferRequest::WaitMode::RESULT_READY` - waits until inference result becomes available
+* `InferenceEngine::IInferRequest::WaitMode::STATUS_ONLY` - immediately returns request status.It does not
+block or interrupts current thread.
+
+Both requests are thread-safe: can be called from different threads without fearing corruption and failures.
+
+Multiple requests for single `ExecutableNetwork` are executed sequentially one by one in FIFO order.
+
+While request is ongoing, all its methods except `InferenceEngine::InferRequest::Wait` would throw an
+exception.
+
+8) Go over the output blobs and **process the results**.
+Note that casting `Blob` to `TBlob` via `std::dynamic_pointer_cast` is not recommended way,
+better to access data via `buffer()` and `as()` methods as follows:
+```cpp
+    for (auto &item : output_info) {
+        auto output_name = item.first;
+        auto output = infer_request.GetBlob(output_name);
+        {
+            auto const memLocker = output->cbuffer(); // use const memory locker
+            // output_buffer is valid as long as the lifetime of memLocker
+            const float *output_buffer = memLocker.as<const float *>();
+            /** output_buffer[] - accessing output blob data **/
+
+```
+
+## Build Your Application
+
+For details about building your application, refer to the CMake files for the sample applications.
+All samples source code is located in the `<INSTALL_DIR>/openvino/inference_engine/samples` directory, where `INSTALL_DIR` is the OpenVINO™ installation directory.
+
+### CMake project creation
+
+1. **Create a structure** for the project:
+``` sh
+project/
+    ├── CMakeLists.txt  - CMake file to build
+    ├── ...             - Additional folders like includes/
+    └── src/            - source folder
+        └── main.cpp
+build/                  - build directory
+    ...      
+```
+
+2. **Include Inference Engine, nGraph and OpenCV libraries** in `project/CMakeLists.txt`  
+[OpenCV](https://docs.opencv.org/master/db/df5/tutorial_linux_gcc_cmake.html) integration is needed mostly for pre-processing input data and ngraph for more complex applications using [ngraph API](nGraph_Flow.md).
+``` cmake
+cmake_minimum_required(VERSION 3.0.0)
+project(project_name)
+find_package(ngraph REQUIRED)
+find_package(InferenceEngine REQUIRED)
+find_package(OpenCV REQUIRED)
+add_executable(${PROJECT_NAME} src/main.cpp)
+target_link_libraries(${PROJECT_NAME} PRIVATE ${InferenceEngine_LIBRARIES} ${OpenCV_LIBS} ${NGRAPH_LIBRARIES})
+```
+3. **To build your project** using CMake with the default build tools currently available on your machine, execute the following commands:
+> **NOTE**: Make sure **Set the Environment Variables** step in [OpenVINO Installation](../../inference-engine/samples/hello_nv12_input_classification/README.md) document is applied to your terminal, otherwise `InferenceEngine_DIR` and `OpenCV_DIR` variables won't be configured properly to pass `find_package` calls.
+```sh
+cd build/
+cmake ../project
+cmake --build .
+```
+It's allowed to specify additional build options (e.g. to build CMake project on Windows with a specific build tools). Please refer to the [CMake page](https://cmake.org/cmake/help/latest/manual/cmake.1.html#manual:cmake(1)) for details.

+# Introduction to the Performance Topics {#openvino_docs_IE_DG_Intro_to_Performance}
+
+This section is a shorter version of the
+[Optimization Guide](supported_plugins/MULTI.md) for the Intel Deep Learning Deployment Toolkit.
+
+## Precision
+Inference precision directly affects the performance. 
+
+Model Optimizer can produce an IR with different precision. For example, float16 IR initially targets VPU and GPU devices, while, for example, the CPU can also execute regular float32.
+Also, further device-specific inference precision settings are available, for example, [8-bit integer](Int8Inference.md) or [bfloat16](Bfloat16Inference.md) inference on the CPU.
+Note that for [MULTI device](supported_plugins/MULTI.md) that supports automatic inference on multiple devices in parallel, you can use the FP16 IR.
+You can find more information, including preferred data types for specific devices, in the
+[Supported Devices](supported_plugins/Supported_Devices.md) section.
+
+## Lowering Inference Precision
+Default optimization is used for CPU and implies that inference is made with lower precision if it is possible on a given platform to reach better performance with acceptable range of accuracy.
+This approach is used for CPU device if platform supports the AVX512_BF16 instruction. In this case, a regular float32 model is converted to [bfloat16](Bfloat16Inference.md) internal representation and inference is provided with bfloat16 layers usage.
+Below is the example command line to disable this feature on the CPU device with the AVX512_BF16 instruction and execute regular float32.
+```
+$ benchmark_app -m <model.xml> -enforcebf16=false
+ ```
+
+## Latency vs. Throughput
+One way to increase computational efficiency is batching, which combines many (potentially tens) of
+input images to achieve optimal throughput. However, high batch size also comes with a
+latency penalty. So, for more real-time oriented usages, lower batch sizes (as low as a single input) are used.
+Refer to the [Benchmark App](../../inference-engine/samples/benchmark_app/README.md) sample, which allows latency vs. throughput measuring.
+
+## Using Async API
+To gain better performance on accelerators, such as VPU or FPGA, the Inference Engine uses the asynchronous approach (see
+[Integrating Inference Engine in Your Application (current API)](Integrate_with_customer_application_new_API.md)).
+The point is amortizing the costs of data transfers, by pipe-lining, see [Async API explained](@ref omz_demos_object_detection_demo_ssd_async_README).
+Since the pipe-lining relies on the availability of the parallel slack, running multiple inference requests in parallel is essential.
+Refer to the [Benchmark App](../../inference-engine/samples/benchmark_app/README.md) sample, which enables running a number of inference requests in parallel. Specifying different number of request produces different throughput measurements.
+
+## Best Latency on the Multi-Socket CPUs
+Note that when latency is of concern, there are additional tips for multi-socket systems.
+When input is limited to the single image, the only way to achieve the best latency is to limit execution to the single socket.
+The reason is that single image is simply not enough
+to saturate more than one socket. Also NUMA overheads might dominate the execution time.
+Below is the example command line that limits the execution to the single socket using numactl for the best *latency* value
+(assuming the machine with 28 phys cores per socket):
+```
+limited to the single socket).
+$ numactl -m 0 --physcpubind 0-27  benchmark_app -m <model.xml> -api sync -nthreads 28
+ ```
+Note that if you have more than one input, running as many inference requests as you have NUMA nodes (or sockets)
+usually gives the same best latency as a single request on the single socket, but much higher throughput. Assuming two NUMA nodes machine:
+```
+$ benchmark_app -m <model.xml> -nstreams 2
+ ```
+Number of NUMA nodes on the machine can be queried via 'lscpu'.
+Please see more on the NUMA support in the [Optimization Guide](supported_plugins/MULTI.md).
+
+## Throughput Mode for CPU
+Unlike most accelerators, CPU is perceived as an inherently latency-oriented device. 
+Since 2018 R5 release, the Inference Engine introduced the "throughput" mode, which allows the Inference Engine to efficiently run multiple inference requests on the CPU simultaneously, greatly improving the throughput.
+
+Internally, the execution resources are split/pinned into execution "streams".
+Using this feature gains much better performance for the networks that originally are not scaled well with a number of threads (for example, lightweight topologies). This is especially pronounced for the many-core server machines.
+
+Run the [Benchmark App](../../inference-engine/samples/benchmark_app/README.md) and play with number of infer requests running in parallel, next section. 
+Try different values of the `-nstreams` argument from `1` to a number of CPU cores and find one that provides the best performance. 
+
+In addition to the number of streams, it is also possible to play with the batch size to find the throughput sweet-spot.
+
+The throughput mode relaxes the requirement to saturate the CPU by using a large batch: running multiple independent inference requests in parallel often gives much better performance, than using a batch only.
+This allows you to simplify the app-logic, as you don't need to combine multiple inputs into a batch to achieve good CPU performance.
+Instead, it is possible to keep a separate infer request per camera or another source of input and process the requests in parallel using Async API.
+
+## Benchmark App
+[Benchmark App](../../inference-engine/samples/benchmark_app/README.md) sample is the best performance reference.
+It has a lot of device-specific knobs, but the primary usage is as simple as: 
+```bash
+$ ./benchmark_app –d GPU –m <model> -i <input>
+```
+to measure the performance of the model on the GPU. 
+Or
+```bash
+$ ./benchmark_app –d CPU –m <model> -i <input>
+```
+to execute on the CPU instead.
+
+For example, for the CPU throughput mode from the previous section, you can play with number of streams (`-nstreams` command-line param). 
+Try different values of the `-nstreams` argument from `1` to a number of CPU cores and find one that provides the best performance. For example, on a 8-core CPU, compare the `-nstreams 1` (which is a latency-oriented scenario) to the `2`, `4` and `8` streams. Notice that `benchmark_app` automatically queries/creates/runs number of requests required to saturate the given number of streams. 
+
+Finally, notice that when you don't specify number of streams with `-nstreams`, "AUTO" value for the streams is used, e.g. for the CPU this is [CPU_THROUGHPUT_AUTO](supported_plugins/CPU.md). You can spot the actual value behind "AUTO" for your machine in the application output.
+Notice that the "AUTO" number is not necessarily most optimal, so it is generally recommended to play either with the benchmark_app's "-nstreams" as described above, or via  [new Workbench tool](@ref workbench_docs_Workbench_DG_Introduction).This allows you to simplify the app-logic, as you don't need to combine multiple inputs into a batch to achieve good CPU performance.
+Instead, it is possible to keep a separate infer request per camera or another source of input and process the requests in parallel using Async API.
+
+## Kernels Tuning for GPU
+
+GPU backend comes with a feature, that allows models tuning, so the workload is configured to fit better into hardware.
+
+Tuning is time consuming process, which internally execute every layer several (or even hundreds) times to find most performant configuration.
+
+This configuration is saved into json-formatted file, whose name can be passed as plugin param to network. GPU backend will process this data to configure kernels for the best performance.
+
+For more details about Kernels Tuning and How-To please refer to [GPU Kernels Tuning](GPU_Kernels_Tuning.md).

+
+## Deployment Challenges
+
+Deploying deep learning networks from the training environment to embedded platforms for inference
+might be a complex task that introduces a number of technical challenges that must be addressed:
+
+* There are a number of deep learning frameworks widely used in the industry, such as Caffe*, TensorFlow*, MXNet*, Kaldi* etc.
+
+* Typically the training of the deep learning networks is performed in data centers or server farms while the inference
+might take place on embedded platforms, optimized for performance and power consumption. Such platforms are typically
+limited both from software perspective (programming languages, third party dependencies, memory consumption,
+supported operating systems), and from hardware perspective (different data types, limited power envelope),
+so usually it is not recommended (and sometimes just impossible) to use original training framework for inference.
+An alternative solution would be to use dedicated inference APIs that are well optimized for specific hardware platforms.
+
+* Additional complications of the deployment process include supporting various layer types and networks that are getting
+more and more complex. Obviously, ensuring the accuracy of the transforms networks is not trivial.
+
+## Deployment Workflow
+The process assumes that you have a network model trained using one of the [supported frameworks](#SupportedFW).
+The scheme below illustrates the typical workflow for deploying a trained deep learning model:
+![scheme]
+
+The steps are:
+
+1. [Configure Model Optimizer](../MO_DG/prepare_model/Config_Model_Optimizer.md) for the specific framework (used to train your model).
+
+2. Run [Model Optimizer](#MO) to produce an optimized [Intermediate Representation (IR)](../MO_DG/IR_and_opsets.md)
+of the model based on the trained network topology, weights and biases values, and other optional parameters.
+
+3. Test the model in the IR format using the [Inference Engine](#IE) in the target environment with provided 
+[Inference Engine sample applications](Samples_Overview.md).
+
+4. [Integrate Inference Engine](Integrate_with_customer_application_new_API.md) in your application to deploy the model in the target environment.
+
+
+## Model Optimizer <a name = "MO"></a>
+
+Model Optimizer is a cross-platform command line tool that facilitates the transition between the training and
+deployment environment, performs static model analysis and automatically adjusts deep learning
+models for optimal execution on end-point target devices.
+
+Model Optimizer is designed to support multiple deep learning [supported frameworks and formats](#SupportedFW).
+
+While running Model Optimizer you do not need to consider what target device you wish to use, the same output of the MO can be used in all targets.
+
+### Model Optimizer Workflow
+
+The process assumes that you have a network model trained using one of the [supported frameworks](#SupportedFW).
+The Model Optimizer workflow can be described as following:
+
+* [Configure Model Optimizer](../MO_DG/prepare_model/Config_Model_Optimizer.md) for one of the supported deep learning framework that was used to train the model.
+* Provide as input a trained network that contains a certain network topology, and the adjusted weights and

+
+## Intermediate Representation
+
+Intermediate representation describing a deep learning model plays an important role connecting the OpenVINO&trade; toolkit components.
+The IR is a pair of files:
+    * `.xml`: The topology file - an XML file that describes the network topology
+    * `.bin`: The trained data file - a .bin file that contains the weights and biases binary data
+
+Intermediate Representation (IR) files can be read, loaded and inferred with the [Inference Engine](#IE).
+Inference Engine API offers a unified API across a number of [supported Intel® platforms](#SupportedTargets).
+IR is also consumed, modified and written by Post-Training Optimization Tool which provides quantization capabilities.
+
+Refer to a dedicated description about [Intermediate Representation and Operation Sets](../MO_DG/IR_and_opsets.md) for further details.
+
+## nGraph Integration
+
+OpenVINO toolkit is powered by nGraph capabilities for Graph construction API, Graph transformation engine and Reshape.
+nGraph Function is used as an intermediate representation for a model in the run-time underneath the CNNNetwork API.
+The conventional representation for CNNNetwork is still available if requested for backward compatibility when some conventional API methods are used.
+Please refer to the [Overview of nGraph Flow](nGraph_Flow.md) describing the details of nGraph integration into the Inference Engine and co-existence with the conventional representation.
+
+## Inference Engine <a name = "IE"></a>
+
+Inference Engine is a runtime that delivers a unified API to integrate the inference with application logic:
+
+* Takes as input the model. The model presented in the specific form of [Intermediate Representation (IR)](../MO_DG/IR_and_opsets.md)
+produced by Model Optimizer.
+* Optimizes inference execution for target hardware.
+* Delivers inference solution with reduced footprint on embedded inference platforms.
+
+The Inference Engine supports inference of multiple image classification networks,
+including AlexNet, GoogLeNet, VGG and ResNet families of networks, fully convolutional networks like FCN8 used for image
+ segmentation, and object detection networks like Faster R-CNN.
+
+For the full list of supported hardware, refer to the
+[Supported Devices](supported_plugins/Supported_Devices.md) section.
+
+For Intel® Distribution of OpenVINO™ toolkit, the Inference Engine package contains [headers](files.html), runtime libraries, and
+[sample console applications](Samples_Overview.md) demonstrating how you can use
+the Inference Engine in your applications.
+
+The open source version is available in the [OpenVINO™ toolkit GitHub repository](https://github.com/openvinotoolkit/openvino) and can be built for supported platforms using the <a href="https://github.com/openvinotoolkit/openvino/blob/master/build-instruction.md">Inference Engine Build Instructions</a>.

+# Known Issues and Limitations {#openvino_docs_IE_DG_Known_Issues_Limitations}
+
+## Multiple OpenMP Loadings
+
+If the application uses the Inference Engine with third-party components that depend on Intel OpenMP, multiple loadings of the libiomp library may occur and cause OpenMP runtime initialization conflicts. This may happen, for example, if the application uses Intel® Math Kernel Library (Intel® MKL) through the “Single Dynamic Library” (<code>libmkl_rt.so</code>) mechanism and calls Intel MKL after loading the Inference Engine plugin.
+The error log looks as follows:
+```sh
+OMP: Error #15: Initializing libiomp5.so, but found libiomp5.so already initialized.
+OMP: Hint: This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results. For more information, please see http://www.intel.com/software/products/support/.
+```
+
+Possible workarounds:
+
+*  Preload the OpenMP runtime using the <code>LD_PRELOAD</code> variable:
+```sh
+LD_PRELOAD=<path_to_libiomp5.so> <path_to your_executable>
+```
+   This eliminates multiple loadings of libiomp, and makes all the components use this specific version of OpenMP.
+
+*  Alternatively, you can set <code>KMP_DUPLICATE_LIB_OK=TRUE</code>. However, performance degradation or results incorrectness may occur in this case.
+
+
+## Old proto compiler breaks protobuf library
+
+With python protobuf library version 3.5.1 the following incompatibility can happen.
+The known case is for Cent OS 7.4
+
+The error log looks as follows:
+
+```sh
+File "../lib64/python3.5/site-packages/google/protobuf/descriptor.py", line 829, in _new_
+return _message.default_pool.AddSerializedFile(serialized_pb)
+TypeError: expected bytes, str found
+```
+
+Possible workaround is to upgrade default protobuf compiler (libprotoc 2.5.0) to newer version, for example
+libprotoc 2.6.1.

+
+## Image Pre-Processing Performance Optimization Issue
+
+As described in [documentation for new API](Integrate_with_customer_application_new_API.md), you can set an image blob of any size to an
+infer request using resizable input. Resize is executed during inference using configured resize algorithm.
+
+But currently resize algorithms are not completely optimized. So expect performance degradation if resizable input is
+specified and an input blob (to be resized) is set (`SetBlob()` is used). Required performance is met for
+[CPU](supported_plugins/CPU.md) plugin only (because enabled openMP* provides parallelism).
+
+Another limitation is that currently, resize algorithms support NCHW layout only. So if you set NHWC layout for an input
+blob, NHWC is converted to NCHW before resize and back to NHWC after resize.

+Inference Engine Memory primitives {#openvino_docs_IE_DG_Memory_primitives}
+=====================================================================
+
+## Blobs
+
+<code>InferenceEngine::Blob</code> is the main class intended for working with memory.
+Using this class you can read and write memory, get information about the memory structure etc.
+
+The right way to create <code>Blob</code> objects with a specific layout is to use constructors with <code>InferenceEngine::TensorDesc</code>.
+<pre class="brush:cpp">
+InferenceEngige::TensorDesc tdesc(FP32, {1, 3, 227, 227}, InferenceEngine::Layout::NCHW);
+InferenceEngine::Blob::Ptr blob = InferenceEngine::make_shared_blob<float>(tdesc);
+</pre>
+
+## Layouts
+
+<code>InferenceEngine::TensorDesc</code> is a special class that provides layout format description.
+
+This class allows to create planar layouts using the standard formats (like <code>InferenceEngine::Layout::NCDHW</code>, <code>InferenceEngine::Layout::NCHW</code>, <code>InferenceEngine::Layout::NC</code>, <code>InferenceEngine::Layout::C</code> and etc) and also non-planar layouts using <code>InferenceEngine::BlockingDesc</code>.
+
+In order to create a complex layout you should use <code>InferenceEngine::BlockingDesc</code> which allows to define the blocked memory with offsets and strides.
+
+## Examples
+
+1. You can define a blob with dimensions {N: 1, C: 25, H: 20, W: 20} and format NHWC with using next parameters:<br/>
+<pre class="brush:cpp">
+InferenceEngine::BlockingDesc({1, 20, 20, 25}, {0, 2, 3, 1}); // or
+InferenceEngine::BlockingDesc({1, 20, 20, 25}, InferenceEngine::Layout::NHWC);
+</pre>
+2. If you have a memory with real dimensions {N: 1, C: 25, H: 20, W: 20} but with channels which are blocked by 8, you can define it using next parameters:<br/>
+<pre class="brush:cpp">
+InferenceEngine::BlockingDesc({1, 4, 20, 20, 8}, {0, 1, 2, 3, 1})
+</pre>
+3. Also you can set strides and offsets if layout contains it.
+4. If you have a complex blob layout and you don't want to calculate the real offset to data you can use methods
+<code>InferenceEngine::TensorDesc::offset(size_t l)</code> or <code>InferenceEngine::TensorDesc::offset(SizeVector v)</code>.<br/>
+For example:
+<pre class="brush:cpp">
+InferenceEngine::BlockingDesc blk({1, 4, 20, 20, 8}, {0, 1, 2, 3, 1});
+InferenceEngine::TensorDesc tdesc(FP32, {1, 25, 20, 20}, blk);
+tdesc.offset(0); // = 0
+tdesc.offset(1); // = 8
+tdesc.offset({0, 0, 0, 2}); // = 16
+tdesc.offset({0, 1, 0, 2}); // = 17
+</pre>
+5. If you would like to create a TensorDesc with a planar format and for N dimensions (N can be different 1, 2, 4 and etc), you can use the method
+<code>InferenceEngine::TensorDesc::getLayoutByDims</code>.
+<pre class="brush:cpp">
+InferenceEngine::TensorDesc::getLayoutByDims({1}); // InferenceEngine::Layout::C
+InferenceEngine::TensorDesc::getLayoutByDims({1, 2}); // InferenceEngine::Layout::NC
+InferenceEngine::TensorDesc::getLayoutByDims({1, 2, 3, 4}); // InferenceEngine::Layout::NCHW
+InferenceEngine::TensorDesc::getLayoutByDims({1, 2, 3}); // InferenceEngine::Layout::BLOCKED
+InferenceEngine::TensorDesc::getLayoutByDims({1, 2, 3, 4, 5}); // InferenceEngine::Layout::NCDHW
+InferenceEngine::TensorDesc::getLayoutByDims({1, 2, 3, 4, 5, ...}); // InferenceEngine::Layout::BLOCKED
+</pre>

+Migration from Inference Engine Plugin API to Core API {#openvino_docs_IE_DG_Migration_CoreAPI}
+===============================
+
+For 2019 R2 Release, the new Inference Engine Core API is introduced. This guide is updated to reflect the new API approach. The Inference Engine Plugin API is still supported, but is going to be deprecated in future releases.
+
+This section provides common steps to migrate your application written using the Inference Engine Plugin API (`InferenceEngine::InferencePlugin`) to the Inference Engine Core API (`InferenceEngine::Core`). 
+
+To learn how to write a new application using the Inference Engine, refer to [Integrate the Inference Engine Request API with Your Application](Integrate_with_customer_application_new_API.md) and [Inference Engine Samples Overview](Samples_Overview.md).
+
+## Inference Engine Core Class
+
+The Inference Engine Core class is implemented on top existing Inference Engine Plugin API and handles plugins internally. 
+The main responsibility of the `InferenceEngine::Core` class is to hide plugin specifics inside and provide a new layer of abstraction that works with devices (`InferenceEngine::Core::GetAvailableDevices`). Almost all methods of this class accept `deviceName` as an additional parameter that denotes an actual device you are working with. Plugins are listed in the `plugins.xml` file, which is loaded during constructing `InferenceEngine::Core` objects:
+
+```bash
+<ie>
+    <plugins>
+        <plugin name="CPU" location="libMKLDNNPlugin.so">
+        </plugin>
+        ...
+</ie>
+```
+
+## Migration Steps
+
+Common migration process includes the following steps:
+
+1. Migrate from the `InferenceEngine::InferencePlugin` initialization:
+```cpp
+InferenceEngine::InferencePlugin plugin = InferenceEngine::PluginDispatcher({ FLAGS_pp }).getPluginByDevice(FLAGS_d);
+```
+to the `InferenceEngine::Core` class initialization:
+```cpp
+InferenceEngine::Core core;
+```
+
+2. Instead of using `InferenceEngine::CNNNetReader` to read IR:
+```cpp
+CNNNetReader network_reader;
+network_reader.ReadNetwork(fileNameToString(input_model));
+network_reader.ReadWeights(fileNameToString(input_model).substr(0, input_model.size() - 4) + ".bin");
+CNNNetwork network = network_reader.getNetwork();
+```
+read networks using the Core class:
+```cpp
+CNNNetwork network = core.ReadNetwork(input_model);
+```
+The Core class also allows reading models from ONNX format:
+```cpp
+CNNNetwork network = core.ReadNetwork("model.onnx");
+```
+
+3. Instead of adding CPU device extensions to the plugin:
+```cpp
+plugin.AddExtension(std::make_shared<Extensions::Cpu::CpuExtensions>());
+```
+add extensions to CPU device using the Core class:
+```cpp
+core.AddExtension(std::make_shared<Extensions::Cpu::CpuExtensions>(), "CPU");
+```
+
+4. Instead of setting configuration keys to a particular plugin, set (key, value) pairs via `InferenceEngine::Core::SetConfig`
+```cpp
+core.SetConfig({{PluginConfigParams::KEY_CONFIG_FILE, FLAGS_c}}, "GPU");
+```
+> **NOTE**: If `deviceName` is omitted as the last argument, configuration is set for all Inference Engine devices.
+
+5. Migrate from loading the network to a particular plugin:
+```cpp
+auto execNetwork = plugin.LoadNetwork(network, { });
+```
+to `InferenceEngine::Core::LoadNetwork` to a particular device:
+```cpp
+auto execNetwork = core.LoadNetwork(network, deviceName, { });
+```
+
+After you have an instance of `InferenceEngine::ExecutableNetwork`, all other steps are as usual.

+# ONNX* Importer API Tutorial {#openvino_docs_IE_DG_OnnxImporterTutorial}
+
+> **NOTE**: This tutorial is deprecated. Since OpenVINO™ 2020.4 version, Inference Engine enables reading ONNX models via the Inference Engine Core API
+> and there is no need to use directly the low-level ONNX* Importer API anymore. 
+> To read ONNX\* models, it's recommended to use the InferenceEngine::Core::ReadNetwork method that provide a uniform way to read models from IR or ONNX format.
+
+This tutorial demonstrates how to use the ONNX\* Importer API.
+This API makes it possible to create an nGraph `Function` object from an imported ONNX model.
+
+All functions of the ONNX Importer API are in the [onnx.hpp][onnx_header] header file.
+
+Two categories of API functions:
+* Helper functions that check which ONNX ops are supported in a current version of the ONNX Importer
+* Functions that read ONNX models from a stream or file and result in an nGraph function, which can be executed using the Inference Engine
+
+## Check Which ONNX Ops Are Supported
+
+To list all supported ONNX ops in a specific version and domain, use the `get_supported_operators` 
+as shown in the example below:
+```cpp
+const std::int64_t version = 12;
+const std::string domain = "ai.onnx";
+const std::set<std::string> supported_ops = ngraph::onnx_import::get_supported_operators(version, domain);
+
+for(const auto& op : supported_ops)
+{
+    std::cout << op << std::endl;
+}
+```
+The above code produces a list of all the supported operators for the `version` and `domain` you specified and outputs a list similar to this:
+```cpp
+Abs
+Acos
+...
+Xor
+```
+
+To determine whether a specific ONNX operator in a particular version and domain is supported by the importer, use the `is_operator_supported` function as shown in the example below:
+```cpp
+const std::string op_name = "Abs";
+const std::int64_t version = 12;
+const std::string domain = "ai.onnx";
+const bool is_abs_op_supported = ngraph::onnx_import::is_operator_supported(op_name, version, domain);
+
+std::cout << "Abs in version 12, domain `ai.onnx`is supported: " << (is_abs_op_supported ? "true" : "false") << std::endl;
+```
+
+## Import ONNX Model
+
+To import an ONNX model, use the `import_onnx_model` function.
+The method has two overloads:
+* <a href="#stream">`import_onnx_model` takes a stream as an input</a>, for example, file stream, memory stream
+* <a href="#path">`import_onnx_model` takes a file path as an input</a>
+
+Refer to the sections below for details.
+
+> **NOTE**: The examples below use the ONNX ResNet50 model, which is available at the [ONNX Model Zoo][onnx_model_zoo]:
+> ```bash
+> $ wget https://s3.amazonaws.com/download.onnx/models/opset_8/resnet50.tar.gz
+> $ tar -xzvf resnet50.tar.gz
+> ```
+
+Once you create the `ng_function`, you can use it to run computation on the Inference Engine.
+As it was shown in [Build a Model with nGraph Library](nGraphTutorial.md), `std::shared_ptr<ngraph::Function>` can be transformed into a `CNNNetwork`.
+
+
+### <a name="stream">Stream as Input</a>
+
+The code below shows how to convert the ONNX ResNet50 model to the nGraph function using `import_onnx_model` with the stream as an input:
+
+```cpp
+ const std::string resnet50_path = "resnet50/model.onnx";
+ std::ifstream resnet50_stream(resnet50_path);
+ if(resnet50_stream.is_open())
+ {
+     try
+     {
+         const std::shared_ptr<ngraph::Function> ng_function = ngraph::onnx_import::import_onnx_model(resnet50_stream);
+
+         // Check shape of the first output, for example
+         std::cout << ng_function->get_output_shape(0) << std::endl;
+         // The output is Shape{1, 1000}
+     }
+     catch (const ngraph::ngraph_error& error)
+     {
+         std::cout << "Error when importing ONNX model: " << error.what() << std::endl;
+     }
+ }
+ resnet50_stream.close();
+```
+
+### <a name="path">Filepath as Input</a>
+
+The code below shows how to convert the ONNX ResNet50 model to the nGraph function using `import_onnx_model` with the filepath as an input:
+```cpp
+const std::shared_ptr<ngraph::Function> ng_function = ngraph::onnx_import::import_onnx_model(resnet50_path);
+```

+You can download the [pre-trained models](@ref omz_models_intel_index) using the OpenVINO [Model Downloader](@ref omz_tools_downloader_README) or from [https://download.01.org/opencv/](https://download.01.org/opencv/).
+
+## Build the Sample Applications
+
+### <a name="build_samples_linux"></a>Build the Sample Applications on Linux*
+
+The officially supported Linux* build environment is the following:
+
+* Ubuntu* 16.04 LTS 64-bit or CentOS* 7.4 64-bit
+* GCC* 5.4.0 (for Ubuntu* 16.04) or GCC* 4.8.5 (for CentOS* 7.4)
+* CMake* version 2.8.12 or higher
+
+To build the C or C++ sample applications for Linux, go to the `<INSTALL_DIR>/inference_engine/samples/c` or `<INSTALL_DIR>/inference_engine/samples/cpp` directory, respectively, and run the `build_samples.sh` script:
+```sh
+build_samples.sh
+```
+
+Once the build is completed, you can find sample binaries in the following folders:
+* C samples: `~/inference_engine_c_samples_build/intel64/Release`
+* C++ samples: `~/inference_engine_cpp_samples_build/intel64/Release`
+
+You can also build the sample applications manually:
+
+> **NOTE**: If you have installed the product as a root user, switch to root mode before you continue: `sudo -i`
+
+1. Navigate to a directory that you have write access to and create a samples build directory. This example uses a directory named `build`:
+```sh
+mkdir build
+```
+> **NOTE**: If you ran the Image Classification verification script during the installation, the C++ samples build directory was already created in your home directory: `~/inference_engine_samples_build/`
+
+2. Go to the created directory:
+```sh
+cd build
+```
+
+3. Run CMake to generate the Make files for release or debug configuration. For example, for C++ samples:
+  - For release configuration:
+  ```sh
+  cmake -DCMAKE_BUILD_TYPE=Release <INSTALL_DIR>/inference_engine/samples/cpp
+  ```
+  - For debug configuration:
+  ```sh
+  cmake -DCMAKE_BUILD_TYPE=Debug <INSTALL_DIR>/inference_engine/samples/cpp
+  ```
+4. Run `make` to build the samples:
+```sh
+make
+```
+
+For the release configuration, the sample application binaries are in `<path_to_build_directory>/intel64/Release/`;
+for the debug configuration — in `<path_to_build_directory>/intel64/Debug/`.
+
+### <a name="build_samples_windows"></a>Build the Sample Applications on Microsoft Windows* OS
+
+The recommended Windows* build environment is the following:
+* Microsoft Windows* 10
+* Microsoft Visual Studio* 2017, or 2019
+* CMake* version 2.8.12 or higher
+
+> **NOTE**: If you want to use Microsoft Visual Studio 2019, you are required to install CMake 3.14.
+
+To build the C or C++ sample applications on Windows, go to the `<INSTALL_DIR>\inference_engine\samples\c` or `<INSTALL_DIR>\inference_engine\samples\cpp` directory, respectively, and run the `build_samples_msvc.bat` batch file:
+```sh
+build_samples_msvc.bat
+```
+
+By default, the script automatically detects the highest Microsoft Visual Studio version installed on the machine and uses it to create and build
+a solution for a sample code. Optionally, you can also specify the preferred Microsoft Visual Studio version to be used by the script. Supported
+versions are `VS2017` and `VS2019`. For example, to build the C++ samples using the Microsoft Visual Studio 2017, use the following command:
+```sh
+<INSTALL_DIR>\inference_engine\samples\cpp\build_samples_msvc.bat VS2017
+```
+
+Once the build is completed, you can find sample binaries in the following folders:
+* C samples: `C:\Users\<user>\Documents\Intel\OpenVINO\inference_engine_c_samples_build\intel64\Release`
+* C++ samples: `C:\Users\<user>\Documents\Intel\OpenVINO\inference_engine_cpp_samples_build\intel64\Release`
+
+You can also build a generated solution manually. For example, if you want to build C++ sample binaries in Debug configuration, run the appropriate version of the
+Microsoft Visual Studio and open the generated solution file from the `C:\Users\<user>\Documents\Intel\OpenVINO\inference_engine_cpp_samples_build\Samples.sln`
+directory.
+
+## Get Ready for Running the Sample Applications
+
+### Get Ready for Running the Sample Applications on Linux*
+
+Before running compiled binary files, make sure your application can find the
+Inference Engine and OpenCV libraries.
+Run the `setupvars` script to set all necessary environment variables:
+```sh
+source <INSTALL_DIR>/bin/setupvars.sh
+```
+
+**(Optional)**: The OpenVINO environment variables are removed when you close the
+shell. As an option, you can permanently set the environment variables as follows:
+
+1. Open the `.bashrc` file in `<user_home_directory>`:
+```sh
+vi <user_home_directory>/.bashrc
+```
+
+2. Add this line to the end of the file:
+```sh
+source /opt/intel/openvino/bin/setupvars.sh
+```
+
+3. Save and close the file: press the **Esc** key, type `:wq` and press the **Enter** key.
+4. To test your change, open a new terminal. You will see `[setupvars.sh] OpenVINO environment initialized`.
+
+You are ready to run sample applications. To learn about how to run a particular
+sample, read the sample documentation by clicking the sample name in the samples
+list above.
+
+### Get Ready for Running the Sample Applications on Windows*
+
+Before running compiled binary files, make sure your application can find the
+Inference Engine and OpenCV libraries.
+Use the `setupvars` script, which sets all necessary environment variables:
+```sh
+<INSTALL_DIR>\bin\setupvars.bat
+```
+
+To debug or run the samples on Windows in Microsoft Visual Studio, make sure you
+have properly configured **Debugging** environment settings for the **Debug**
+and **Release** configurations. Set correct paths to the OpenCV libraries, and
+debug and release versions of the Inference Engine libraries.
+For example, for the **Debug** configuration, go to the project's
+**Configuration Properties** to the **Debugging** category and set the `PATH`
+variable in the **Environment** field to the following:
+
+```sh
+PATH=<INSTALL_DIR>\deployment_tools\inference_engine\bin\intel64\Debug;<INSTALL_DIR>\opencv\bin;%PATH%
+```
+where `<INSTALL_DIR>` is the directory in which the OpenVINO toolkit is installed.
+
+You are ready to run sample applications. To learn about how to run a particular
+sample, read the sample documentation by clicking the sample name in the samples
+list above.

+Using Shape Inference {#openvino_docs_IE_DG_ShapeInference}
+==========================================
+
+Inference Engine takes two kinds of model description as an input: [Intermediate Representation (IR)](../MO_DG/IR_and_opsets.md) and [nGraph::Function](nGraph_Flow.md) objects. 
+Both should have fixed input shapes to be successfully loaded to the Inference Engine.
+To feed input data of a shape that is different from the model input shape, resize the model first.
+
+Model resizing on the stage of <a href="_docs_MO_DG_prepare_model_convert_model_Converting_Model_General.html#when_to_specify_input_shapes">IR generation</a> or [nGraph::Function creation](nGraphTutorial.md) is the recommended approach. 
+OpenVINO™ provides the following experimental methods for runtime model reshaping:
+
+1.  Setting a new input shape with the `InferenceEngine::CNNNetwork::reshape` method
+ 
+	`InferenceEngine::CNNNetwork::reshape` method updates input shapes and propagates them down to the outputs of the model through all intermediate layers.
+    
+    Shape propagation for `InferenceEngine::CNNNetwork` objects created from `nGraph::Function` or IR of the version 10 works through the `nGraph` shape inference mechanism. 
+    `InferenceEngine::CNNNetwork` objects created from lower IR versions are considered deprecated and may be reshaped incorrectly or give unexpected results.
+ 
+	To keep the v10 IR resizable by the `InferenceEngine::CNNNetwork::reshape` method, convert the model with the additional Model Optimizer key `--keep_shape_ops`.
+ 
+2.  Setting a new batch dimension value with the `InferenceEngine::CNNNetwork::setBatchSize` method
+    
+    The meaning of a model batch may vary depending on choices you made during the model designing. 
+    The `InferenceEngine::CNNNetwork::setBatchSize` method deduces index of batch dimension relying only on the input rank. 
+    This method does not work for models with a non-zero index batch placement or models with inputs without a batch dimension. 
+
+    Batch-setting algorithm does not involve shape inference mechanism.
+    Batch of input and output shapes for all layers is set to a new batch value without layer validation.
+    It may cause both positive and negative side effects.
+ 
+    Due to the limitations described above, the current method is recommended for simple image processing models only.
+
+
+Practically, some models are not ready to be resized. In this case, a new input shape cannot be set with the Model Optimizer or the `InferenceEngine::CNNNetwork::reshape` method.
+
+## Troubleshooting Resize Errors
+
+Operation semantics may impose restrictions on input shapes of the operation. 
+Shape collision during shape propagation may be a sign that a new shape does not satisfy the restrictions. 
+Changing the model input shape may result in intermediate operations shape collision.
+
+Examples of such operations:
+- <a href="_docs_MO_DG_prepare_model_convert_model_IR_V10_opset1.html#Reshape">`Reshape` operation</a> with a hard-coded output shape value
+- <a href="_docs_MO_DG_prepare_model_convert_model_IR_V10_opset1.html#MatMul">`MatMul` operation</a> with the `Const` second input cannot be resized by spatial dimensions due to operation semantics
+
+Model structure and logic should not change significantly after resizing.
+- The Global Pooling operation is commonly used to reduce output feature map of classification models output.
+Having the input of the shape [N, C, H, W], Global Pooling returns the output of the shape [N, C, 1, 1].
+Model architects usually express Global Pooling with the help of the `Pooling` operation with the fixed kernel size [H, W].
+During spatial reshape, having the input of the shape [N, C, H1, W1], Pooling with the fixed kernel size [H, W] returns the output of the shape [N, C, H2, W2], where H2 and W2 are commonly not equal to `1`.
+It breaks the classification model structure.
+For example, [publicly available Inception family models from TensorFlow*](https://github.com/tensorflow/models/tree/master/research/slim#pre-trained-models) have this issue.
+
+- Resizing the model input shape may significantly affect its accuracy.
+For example, Object Detection models from TensorFlow have resizing restrictions by design. 
+To keep the model valid after the reshape, choose a new input shape that satisfies conditions listed in the `pipeline.config` file. 
+For details, refer to the <a href="_docs_MO_DG_prepare_model_convert_model_tf_specific_Convert_Object_Detection_API_Models.html#tf_od_custom_input_shape">Tensorflow Object Detection API models resizing techniques</a>.
+
+## Usage of Reshape Method
+
+The primary method of the feature is `InferenceEngine::CNNNetwork::reshape`.
+It gets new input shapes and propagates it from input to output for all intermediates layers of the given network.
+The method takes `InferenceEngine::ICNNNetwork::InputShapes` - a map of pairs: name of input data and its dimension.
+
+The algorithm for resizing network is the following:
+
+1) **Collect the map of input names and shapes from Intermediate Representation (IR)** using helper method `InferenceEngine::CNNNetwork::getInputShapes`
+
+2) **Set new input shapes**
+
+3) **Call reshape**
+
+Here is a code example:
+```cpp
+    InferenceEngine::Core core;
+    // ------------- 0. Read IR and image ----------------------------------------------
+    CNNNetwork network = core.ReadNetwork("path/to/IR/xml");
+    cv::Mat image = cv::imread("path/to/image");
+    // ---------------------------------------------------------------------------------
+
+    // ------------- 1. Collect the map of input names and shapes from IR---------------
+    auto input_shapes = network.getInputShapes();
+    // ---------------------------------------------------------------------------------
+
+    // ------------- 2. Set new input shapes -------------------------------------------
+    std::string input_name;
+    SizeVector input_shape;
+    std::tie(input_name, input_shape) = *input_shapes.begin(); // let's consider first input only
+    input_shape[0] = batch_size; // set batch size to the first input dimension
+    input_shape[2] = image.rows; // changes input height to the image one
+    input_shape[3] = image.cols; // changes input width to the image one
+    input_shapes[input_name] = input_shape;
+    // ---------------------------------------------------------------------------------
+
+    // ------------- 3. Call reshape ---------------------------------------------------
+    network.reshape(input_shapes);
+    // ---------------------------------------------------------------------------------
+
+    ...
+
+    // ------------- 4. Loading model to the device ------------------------------------
+    std::string device = "CPU";
+    ExecutableNetwork executable_network = core.LoadNetwork(network, device);
+    // ---------------------------------------------------------------------------------
+
+
+```
+Shape Inference feature is used in [Smart classroom sample](@ref omz_demos_smart_classroom_demo_README).
+
+## Extensibility
+
+Inference Engine provides a special mechanism that allows to add the support of shape inference for custom operations. 
+This mechanism is described in the [Extensibility documentation](Extensibility_DG/Intro.md).
